light clothes, but something to cover in the chilly evenings if you are visiting out of the summer season
Toiletries and Medical Supplies: lots and LOTS of sunscreen, after sun body milk, pills for diarrhea
Photo Equipment: besides the usual photo/filmiong equipment, be sure to have underwater camera! If you don't have it, you ca easily get one there, they are cheap, 60 to 100 pounds (depends if you want one time use, or to use more times), which is 10-15$.Then you'll be able to take pretty photos like this one!
Camping/Beach/Outdoor Gear: hats against the sun, sun glasses, snorkeling equipment (flippers, masks, breathing pipe, even a diver suit if you prefer)
Luggage and bags:
A big valise for putting all your presents!

Toiletries and Medical Supplies: For all people who are drinking water from the tap I advice you : take imodium (loperamidum) or another anti-diarrhoea with you.
I promise you that you need it!
When it is to bad you can take an antibioticum such as ciproxine (ciprofloxacine 250 mg)
And for stomach ache take motilium (domperidonum).
If you have only cramp on your intestine you can take ercefuryl (nifuroxazide).
Please don`t forget your sunmilk you shall need I promise!
