• Some stores and hotels accept credit card payments. But other stores only accept cash or charge an extra 7% if you use a credit card. There are no banks or ATMs on Crooked Island, so make sure to bring enough cash.
• Sand flies and mosquitoes will eat you alive when they come out just before sunset or after a rain shower or storm. So bring plenty of DEET containing mosquito spray or buy it as soon as you arrive. I used a non-DEET creme at first and got bitten a lot.
• Even if you use DEET, chances are that sand flies will bite you. Their bites itch and it is nearly impossible to resist the urge to scratch which can lead to infections. The itching may keep you awake at night. A good temporary remedy is Hydrocortisone cream. You should definitely bring some or buy it as soon as you arrive.
• Crooked Island is large and distances between different points of interest may be too big for a leisurely bicycle ride, especially considering the heat in the daytime and the relentless sand flies in the evening. So chances are that you will need a rental car at some point during your stay. And that means that you need to bring your Driver's License. Be advised that you need to be at least 24 years old to drive a car on Crooked Island.
