I head down to the Caribbean in a few weeks. I'll be bringing a Fuji GSW690, Fuji GW690, Holga Pano, a Diana, (now Flying Camera has me thinking of bringing my Rollei 3.5f, too). Part of my trip is to shoot a job for a hotel, but the rest of the time is mine to do as I please. I'll be shipping 100+ rolls of 120 down ahead of time. I don't know how much film I'll use, but better too much than too few. 120 can't be found on the island.
One of my favorite parts of doing a lot of shooting, on vacation, is having months of darkroom work to do upon my return. It effectively extends the experience, as the sights, sounds, aromas, come back to me while printing.
