Any workout/running shorts. My Nike tempo shorts dry quickly. I wouldn't go out and buy a pair specifically for this trip, though. Chances are you'll dry off pretty quickly in the sun and/or with a towel, and you can put on your regular shorts or cover up right afterward.
I love my Columbia SPF shorts. They have zip off legs if you will be somewhere buggy and damp. I usually leave the longer zip off bottom at home, though, and just wear the shorts. I love that the pockets are big enough and have a zipper to hold waterproof baggies for money and passport copies. I've worn them a lot, and they still look great. I bought mine at Bass Pro Shop, but I'm sure you could find them anywhere.
I just took these to St. John and ended up wearing them every single day. They dried really quickly after the beach, I washed them in the sink every night and they were dry again by morning. I'm buying two more pairs.
