No high heels! ( had one girl bring 3 pairs!)
Lots of sunscreen!
I always bring a pack of bar wipes. Better than paper towels to me and we just chuck them when we are done.

Spices from home. I go to bulk at my store and put them in little baggies.
A waterproof wallet or bag to carry $$$ credit cards etc.
