All the suites I've been in have been relatively dry? I dont see a hotel being very successful renting wetsuites?
Not sure how much you can get them for...go look around on e-bay. Just make sure you spell it correctly or you may not find what you're looking for...
BARE makes a really good dry suit...laxtex seals around the arms , legs, and neck seem to work the best. I have neoprene leg and neck seals on mine that aren't really that water tight, so I don't suggest getting one like that.
