This morning, royal caribbean and celebrity cruises saying they'll restart operations in June, but not from American shores. Royal caribbean from the Bahamas, celebrity from St. Maarten. I think people have a lot of optimism about the future and their ability to see the world again. Reporter: The CEO of celebrity cruises, Lisa lutoff-perlo speaking exclusively with "Gma." It was over a year ago when covid outbreaks shut down the cruise industry and in your case, every single passenger and crew member must be vaccinated. Every guest and our crew must be vaccinated if they're 18 or older and for children they will be required to have a negative pcr test within 72 hours of the cruise as well. One of the things our guests have told us when they come back they don't want their experience to be altered. Reporter: Lisa says it's too early to know what covid protocols will look like in June but that some changes are permanent like cleaning procedures and the air filtration systems. Those will go on into perpetuity. We've modified our medical centers on board just to be able to take care of different things we didn't anticipate in the past when we built them. Reporter: One of the biggest changes, what Lisa calls a robust contact tracing program. So it's going to be very easy to know where those people have been and who they've been with. Reporter: The CDC had said in October that cruise lines would have to run test cruises with volunteer passengers on board before setting sail from America. But -- The world has changed so much since October, especially the vaccines have changed and really been a game changer for all of us so we'll see. Reporter: And the CDC telling us overnight that its conditional sail order is still in effect until November but we should expect some new guidance on that very soon. Meanwhile, Lisa says she is confident that they are ready to do this safely. Dan. Ready to do it safely, gio, thank you very much.
