We have always had a PnP that was either brand new - or in very good condition so to those who are yet to arrive don't worry. If housekeeping should bring you one that you don't want, have them bring another. The Deluxe resorts, Dolphin and Coronado Springs offer a full size crib but you have to ask for it. In rare circumstances you **may** be able to get a full size at another resort if you need one.
In 10 years of trips, with my kids and various neices and nephews we have never had a problem with cribs. My sil used a PnP in December and she said it still had the original packaging on it. My neice was fine in the PnP but the prior December she requested and got a full size crib for my nephew at CR.
I always bring my own sheets and any lovies for the kids, I bring a full size and a PnP so the feel and smell will be familiar and I know its clean.
OP= I love your trip report, thanks for taking the time. I don't want to step on your thread but just want ease any worries of those yet to go.
