You’re making the right choice NOT going AI. El Cid is good but i do not like high rises and I hate the tiny elevators.
Casa Del Mar is my Go-To hotel for 29 years of traveling there. I LOVE it there.
Dive Op – Try Dive With Martin – small groups, excellent service.
Are there any highly recommended dive sites specifically with the best chances of seeing Sharks, big wildlife, Pelagics, etc.? Or that's all really just random luck?...
Maracaibo, Punta Sur are your best bets for big animals. If you want to see amazing a big animals, book a trip on Red Sea Aggressor I and do the Brothers Itenerary. It was so spectacular I bet I will be bored in Cozumel this October.
Most of my 40+ dives are off Key Largo, Pompano Beach
No offense, but I think Florida diving sucks. Just my opinion
