I'm planning a trip for the end of this month, but haven't yet decided on a destination. I've narrowed it down to either Puerto Rico or Jamaica and would like some help with estimating costs. Hotel and flights I've figured out, but what I really need help with is budgeting for activities, and more importantly, food.

In Puerto Rico, I'm planning on staying in either the Condado beach area or the Isla Verde beach area of San Juan. I'm only staying for a few days, so most of the food and activities would be confined to around that area. First, for two budget travellers, how much should we expect to pay per person per meal? Are prices pretty much US city prices? Or are they a bit cheaper? Also, for activities like water sports, (snorkeling, kayak rentals, jet skii, parasailing), or trips to Old San Juan, the Bacardi distillery, how much do things like that run.

For Jamaica, I'm thinking of either staying in the Negril Beach area, or the Montego Bay area, near the "hip strip." Again, how much should we expect to pay for food? Are prices jacked up because it's a big tourist center?

Thanks for any help you can give.
