The no-refunds rage continues — this time it’s folks on the frontlines helping us fight coronavirus who are getting screwed, and it’s all because a cruise line won’t budge.

TMZ has learned … Royal Caribbean Cruises is NOT refunding a bunch of nurses who were supposed to board one of its behemoth boats this year for a networking convention called NURSECON at Sea, which was canceled as a result of the COVID-19 outbreak.

It sucks, ’cause it’s left a lot of cash-strapped RNs pissed off and wanting their money back. They’re getting a rain check for another event down the line, but that’s not cutting it with some of the heroes who want their money back, and STAT.

According to a letter NURSECON brass sent to ticket holders for the conference, it’s spelled out pretty clearly … anybody who was going to NURSECON 2020 (which was at first postponed, later canceled) will get to join any NURSECON voyage in the future through 2023. They’ll also get cruise ship spending credit — up to $100 worth.

And, if nurses who were going ended up shelling out cash for extra vacay packages — excursions, drink and meal plans, etc. — Royal Caribbean WILL refund them for that — but not for the big-ticket item … the cost of the cruise.

That’s about it … no mention of a refund in full for the trip itself this year. It wasn’t NURSECON’s decision, however, as sources familiar with the negotiations between that company and Royal Caribbean tell us, it’s actually RC Cruises honchos who wouldn’t give the cash back. So, if there’s someone to be mad at, it’s the cruise line.

For the record, a rep for NURSECON doesn’t see any blame to go around for anybody involved, insisting the rescheduled cruises and cruise credit was the best option for all parties, insisting that most of their patrons (the nurses) are actually pleased with the deal.

That’s not how some of the nurses we spoke with directly felt. We’re told the no-refund policy is a slap in the face — and a promise for a future sail isn’t making up for it either.

It would be incredibly cruel for Kate McKinnon to use real cats for her new show … so says “Tiger King” star Carole Baskin who implores the actress to choose a different route.

A rep for Carole’s Big Cat Rescue tells TMZ … the org would very much feel like it would be cruel to use real big cats in a television series about cruelty to big cats. The org suggests Kate to instead utilize computer-generated imagery (CGI) of cats in the show rather than forcing real big cats to suffer just to entertain the audience.

ICYMI … Kate — who plans to star as Carole — has had a project in the works since November based on the popular Wondery podcast, “Joe Exotic.” The enormously popular Netflix doc “Tiger King” has since turned Kate’s project a hot commodity, but she’s also now in the crosshairs of wild animal conservationists.

The rep for Big Cat Rescue says, “We hope McKinnon has a passion for animals and that her series will focus on the horrible lives captive big cats lead when exploited by breeders like Joe Exotic. We further hope she urges the public to support the Big Cat Public Safety Act that would end the cub petting abuse in America.”

PETA, which for years had been working to shut down Joe Exotic, has also come out echoing Big Cat Rescue’s sentiments … pleading with Kate and her producers “to use only CGI, animatronics, or even existing footage of big cats and other animals.”

John Callahan of ‘All My Children’ fame has died.

The longtime soap star passed away Saturday after suffering a massive stroke at his Palm Desert, CA home … according to his rep. On Friday, paramedics were called to his home and he was transferred to a hospital in Rancho Mirage, where he was put on life support.

Callahan’s rep says his death is NOT related to COVID-19 — but notes that nonetheless, some of John’s family members were only able to see him for a short while due to hospital restrictions currently in place all over the country because of the coronavirus.

His ex-wife and former ‘AMC’ co-star, Eva La Rue says … ” We are extremely saddened and distraught over the loss of John.” She continued, “He was my great friend, co-parent and an amazing father to Kaya. The absence of his bigger than life, gregarious personality will leave a hole in our hearts forever. Words cannot express the shock and devastation we are feeling at this time. The Yankees just lost one of their greatest fans.”

John played Edmund Grey on the hit show for years, starring in his role from 1992 all through 2005. He also acted on the daytime drama “Santa Barbara” for a couple years in the ’80s as well as ‘Falcon Crest’ in the early ’90s. He also had recurring roles on ‘Days of Our Lives’ dating back to the late ’80s all the way up until 2010.

The guy had 34 acting credits to his name. He’s survived by his daughter, Kaya.

Philadelphia 76ers partner Michael Rubin came up with a creative way to help those fighting the coronavirus pandemic — by turning baseball jerseys into masks and gowns!!

Rubin’s Fanatics company — which makes official MLB unis — has halted all jersey production and instead, they’re using the materials for the jerseys to make essential products for frontline workers in Pennsylvania.

Rubin said the PA governor hit him up asking for help … and the dude delivered, saying he’s planning to make 1 million masks and gowns to help Pennsylvania and eventually more states in need.

The finished product is actually pretty dope … with the Phillies and Yankees pinstripes clearly recognizable in a new form.

“Thanks to @MLB Commissioner Rob Manfred for not only agreeing to halting production of MLB jerseys, but also doing everything possible to make this happen as quickly as possible!!” Rubin tweeted.

“And thanks to our incredible associates who raised their hands and wanted to be part of the effort to help the frontline heroes in this war stem the spread of the virus!!”

As the coronavirus pandemic continues to wreak havoc on the world, a cruise ship company continues to get hit with lawsuits … 3 more former passengers are the most recent plaintiffs.

According to new legal docs … Jeffrey and Anabel Jones, along with Eddy Castellanos, want at least $1 million in damages, claiming Princess Cruise Lines was grossly negligent in allowing them to travel on the Grand Princess cruise ship when it allegedly knew there would be coronavirus exposure.

A significant part of their argument — according to the suit — is what happened on another PCL cruise ship … the Diamond Princess. As you’ll recall, the Diamond was quarantined off the coast of Japan due to coronavirus concerns BEFORE the Grand set sail from San Fran and was quarantined in the Bay Area waters for a week.

The 3 passengers claim PCL should have handled the situation better based on what happened with the Diamond, but instead … they botched it.

Furthermore, the defendants claim an email was sent to former PCL passengers on February 25 to inform of the risk of coronavirus … but they received no such email. They claim if they had gotten word of it, they would have disembarked from the cruise at the next stop in Honolulu.

Also, just like in the suit first filed by Ronald and Eva Weissberger on March 9, the new suit alleges the ship’s staff KNEW at least 2 other passengers with coronavirus had just disembarked from a previous voyage. Despite this, there was no testing done and the screening process was totally insufficient.

There is a quiet panic going around behind the scenes at the House of Representatives because some members tell TMZ they sounded a warning 3 weeks ago about the Capitol being unsafe but they weren’t heeded … and now some fear they have the coronavirus.

The members we spoke with — who only wanted to talk on background — tell us, about 3 weeks ago when the problems associated with coronavirus started blowing up they began talking about limiting or excluding visitors from the Capitol.

It was an especially busy time, because the House was putting together spending bills and people were flying in from all over the country to lobby members. There were also lots of visitors who came by and interacted with a number of members. We’re told the hallways were packed.

One congressman told us, “No one took this seriously. Leaders from both sides initially said they didn’t want to panic people. We’re told the leaders ultimately consulted the Congressional doctor, but as one congressman said, “He was scared to make a decision because he was afraid he would trigger a national panic.”

A congressman we spoke with says he believes he has the virus and is exhibiting mild symptoms and he has self-quarantined. He also says, “I think lots of us [representatives] are going to get it.”

The House is currently not in session, but there’s a big problem. The Senate is in session and is hopefully going to pass a relief bill soon. The House members have gone home, and the only way they can approve the bill without flying to D.C. is if the vote is unanimous.

If one member wants to vote no on the bill, the traditional solution would be for members to fly to D.C. to cast their votes. But, putting 435 people on airplanes — especially when there’s fear some of the members have or were exposed to the virus — it’s super risky. We’re told there’s talk of flying 40 at a time or figuring out some way of keeping people away from each other.

No decisions have been made on what to do if the vote is not unanimous.
