We were at BWV a couple of weeks ago in a 2 br; both cribs had sheets laying on top of them in the closet. I touched one of them, just curious if it was soft or not (my kids are too old!), it was ok but I'd probably bring my own. I brought my own King size sheet for my husband and I, for comfort, so if we were going to use the portable crib I'd bring my own. You can put Disney's on first, then yours! This is what we do for the King, just put ours on top.
As far as privacy for the baby, can you go out on the balcony while she's falling asleep?
