Hmm, theres a list on holiday hints and tips were it gives you the option to print out what things you need to pack.
how about the usual clothes, flipflops,underwear, swimwear, evening wear ( but i suppose you will already have packed them)
Hair dryer, suncream, aftersun, hair bobbles, a couple of towels to see you through the first day ( dont fancy shopping as soon as we get there) , soap, shampoo, deordorant (to see you through a couple of days) then you can always buy more whilst your there. waxing strips( if you use them) , hair brush, mosquito spray.
Im sure there are more things, but these are just things from the top of my head.
Also, pack tour travellers cheques, passports, tickets in your hand luggage.
