The next cheapest is Caribbean Beach because they have a fifth sleeper though I'm not sure even my shortest daughter at 5'4" would fit.
Just to let you know my experience with this. I'm 6'2 near 300 pounds and I slept on the pull down at CBR for a week. I slept just fine too. Wasn't as comfortable as the beds, and my feet hung off a bit when stretched out (luckily I mostly sleep with my legs curled), but I had absolutely no issues getting a good night sleep.
