When we visited in March of 2017, we traveled with an infant. We actually purchased a cheap pack-n-play at a local Walmart for about $40 and used that, since there was no crib available. When we left, we donated the pack-n-play to the front office of the resort, so you might ask them if it is still available!
Not sure. We didn't have an infant in our party.
Just called, they said they have pack and plays available.
