If you've never been to the island, my biggest advice is to bring small bills. Make sure they are not written on or torn. We are from the United States so they took our currency. It just couldn't be written on or torn. The banks won't take it otherwise. The island is very relaxed and laid back so be ready for that. We always rent a golf cart because I prefer it, but a bicycle gets you around just as easily. Everyone is friendly so you will makes friends fast.
The best Sunset is at Iguana Reef. The best pizza is at Suggestion Gormet. Do a sunset cruise and a night snorkel. We usually sail with Ragga Sail and we love them. It's a blue cabin right by Paradiso Cafe.
