Years ago Disney had a crib that was available for rooms, however, as far as I am aware, they now only offer pack and plays. We always received them in good shape and clean, however I always washed them down myself before using. You can also get pack and play travel covers at specialty baby stores - it’s like a sheet that wraps around the pack and play so your baby never touches the actual unit.
Bring your own bedding, Disney crib bedding is sparce, sometimes not offered, and we found to not be enough to keep a little one warm in an air conditioned room (we also felt it helps a little one sleep better to have blankets that smell like home).
Disney does offer bed rails, which would make for a more comfortable sleep if your child is okay with being in a bed. Pack and Plays are very hard and uncomfortable.
