PANCHITA, HOLA, johnin denver here been to both ambergris and caulker and 2 totally different experiences. and have done both quite a few times and like both alot.. for agood time with a lot of island activity and yet still the quiet that settles in by 10 or so ambergris is great.. you can still find clubs rockin if you want to... if you want to have the sleepy island that really has little to do after dinner caulker is cool and i have spent a week there unwinding noproblem. on caulker i like BIG FISH DIVERS for my diving/snorkeling. on caulker i stayed sooper cheap the last time at the CONCH SHELL HOTEL, 400.00 for the week with 5 days 2 tank dives i paid for my bc and weights. but what a deal. you can stay at lilys for 65 to 75 a nite w/ fridge and i think set up a dive pack if you want. I use amigos del mar a great group and they treat you well with coffee in the am andjuice and treats at your interval back on shore. check em out you'll like em john
