Roatan, Honduras has CoCo View Dive Resort. I've been there 3 times and my husband twice. CoCo View is the most frequently returned-to resort in the world. Once you've been there, you fall in love withj it. Your 10th visit is free.

Each couple stays in a cabana which is over the actual Caribbean water. The room is simple, but very clean and well kept. There is unlimited shore diving all day and night. Each diver gets a morning boat ride to 2 destinations and an afternoon boat ride with 2 destinations. The dive masters are awesome. They take you to the animals' homes. Wreck dives are there, as well as reef and wall dives are awesome. It is a good place to get certified on anything and everything you would like.
Diving is so very convenient. Yourr dive locker is just feet away from the dive boats. They fill up water tanks for you. Dive Master and boat captain hook and lift up the tanks.
The photo, equipment repair, gift shops, restaurant, and bar is always open. pool and ping pong at night. 3 meals included with price. I could go on forever.
Sea turtles, goliath grouper, octopus, tarpon, sharks, rays, toad fish, eels and anything else you want to see is there.
I hope some day , if you haven't been, you consider CoCo View as your dive choice.
