First Timers Things to Bring
For the First Timers I would bring
Sunscreen - the sun is very strong. Don't get burnt on the first day
Small bills or currency. Not needed at the resort but there are needed when you try some things off of the resort or for bargaining with the locals. They will first try and charge you ten times as much. Bargain them down about 90%.
Under-water or waterproof camera. It will be useful at Dunn's River Falls or snorkeling. If you don't have on the guides at the Falls held on to mine and it did not get wet and they took pictures of us with it.
Water shoes or aqua socks. Again for the Falls and if needed some water sports.
If I think of anything else I'll fill you in.
