We stayed at the WL with DS in December. He was 2 1/2 at the time. He was still sleeping in his crib at home at the time. He never tried to climb out of his crib, so we just kept him in there until he did (which was a few months later).
When we went in December, it was me, DH, my mom, and DS. DS actually slept on the floor. We brought his nap mat from daycare and folded the extra blanket on the floor for him to sleep on and gave him the exta pillow. He used his blanket from home to cover himself. After the first day, mousekeeping noticed what we did and actually "made" his bed and even included a comforter for him! He did fine down there. I was a little worried about him sleeping on the floor, but then I realized with all the blankets, that was probably softer than the pack n play!
