Caribbean. I’ve been there 3 times. You’re not missing anything by not going there.
Cozumel is almost on every itinerary and is always fun for diving or snorkeling.
Belize has been fun.
Grand Cayman is one of the higher end stops and is also good for snorkeling or diving.
Hopefully it all works out for you. It’ll be interesting to see how the cruise industry adapts to everything going on.
