Our DS does not like to sleep or even sit in a pack-n-play. He just tosses and turns all night because he is so used to having a crib to move around in. We stayed at the Contemporary in September and requested a tried and true crib for our room. I called over and over again just to be sure that we would have a crib, not a pnp. I was assured there would be one in our room. We packed our own crib sheets and DS breathable bumper to make it more like home. When we arrived my DSIL had a crib in her room but our room had a pnp. I asked the CM to find a crib since we were guaranteed one and they did everything they could to find it. Finally a mousekeeper came with the crib looking at me like I was nuts. He told me that he had to go to a storage unit at another Disney hotel to get this crib and not to let it out of my sight!
I was so thankful because I knew DS would sleep so much better. If you are staying on property I know they have them but it can be hard to track one down. Just be persistant. Our crib was metal with high ends and fixed sides. DS slept like a dream every night! I didn't feel weird about borrowing the crib (knowing all the stories behind bad cribs) because there were no drop-down sides and DH checked all the screws and parts before we put DS in it.
