Save some money before you come to Provincetown. The internship is unpaid, housing is $750 for the summer, and groceries are expensive. The Work Center provided some opportunities to make money throughout the summer (housekeeping, gallery sitting, fundraisers, modeling), but it's nice to have some back-up cash.
On that note, look for a part-time job a couple weeks after you get there. You'll know the schedule by then, and there'll be plenty of positions open. People will hire you if they know you're interning with FAWC.
