Hmm... to me, there are two aspects to this: the vacation itself, and the 'cost'.
For the vacation, I think I'd prefer the tropical resort. Fancy hotels are really nice, and tempting, but the risk that they'd be weird about bare feet puts me off a bit, plus I dunno... it just seems less appealing.
For the 'cost'... my favorite is the oral sex for meals, actually. So if I could do the tropical resort, and give oral for meals, that'd be ideal! But otherwise, strictly from the options listed, I'd go with Option A: the tropical resort, and I hand in all clothing at the gate.
