For some travelers, itsy bitsy bikinis or revealing Speedos just don’t cut it — a vacation isn’t a vacation without a little nudity. Luckily for them, these hotels are redefining casual dress with policies that let guests bare it all (or almost all).

Not everyone’s nude-y travel preferences are alike, and a wide range of resorts let guests button down — from an uninhibited, swingers-friendly paradise, to a polished luxury resort with a surprising naughty side.

So take a peek — a little voyeurism never hurt anyone.
