Wow, I didn't know Roatan had an underwater museum. Check out this article. http://www.atlasobscura.com/places/bay-islands-underwater-museum
We will definitely visit next time we are there. You should too. While you are on Roatan, rent our beautiful, Bali inspired 3 bedroom, 2 bath villa, with it's own private pool and mere steps from the beach.
