You said boardwalk so I presume you mean the under the TV pull down murphy in the villas and not the sleeper sofa at the Inn. We've stayed at BWV, CBR and POR all with the same pull down murphy beds under the TV, there's no way anyone over 5'3" would/could sleep on that bed for longer than 1-2 nights and in reality, wouldn't want to. I know 18 year olds are more flexible/roll with the punches than other adults but my daughter last slept on one of these when she was 12, maybe nearing 5' tall and about 80lbs and she said it's not that comfortable. She fit but now at 14 and about my size, she won't do it anymore. I'm 5'3", 118lbs and there's no way I'd sleep on that unless I had no other choice. If it's for a short trip, sure you could make it work but at 5'11", they'll be cramped and hanging off of the bed.
