Hello! All you will need is a few t-shirts and comfy shorts. I wore my Birkenstocks the whole time. They were easy to wear through airport security! You will need cash...brings lots of ones and fives as many of the places you will need the cash don't make change!. You will need it for shopping and tipping people (hotel bell boys, OCC drivers, taxi drivers, etc.) We brought $200 and spent every dime of it. I recommend some Phazyme and liquid pain medicine. I brought Gas-X strips but they did not work for me. Truelytangledgirl gave me some Phazyme and it worked great! You may also want to bring some books or magazines and an I-Pod or MP3 player. Remember to pack your liquids (meds, shampoos, etc.) in small containers and put them in a quart sized ziploc. These are the requirements for the airport! I left all my jewelry at home. I know this is a lot of random info, but I hope it helps!!!
