@Susan1188 --we provide a pac-n-play and a travel crib, the mattress that comes with both is generally just a pad. I do also provide a crib mattress. I provide a waterproof mattress cover, 2 mattress pads, 2 fitted sheets, and a variety of blankets. My thought is that babies do wet the bed etc and sometimes things need to be changed in the middle of the night or whatever. My goal is to make it as convenient as possible for the guest. I do not put any of this together for them--due to the crib is set up differently dependent on weight of child. I actually put protective mattress covers on every mattress and waterproof mattress pads on the bunk beds--because I expect mainly children to be sleeping on them. I also leave a complete change of bedding available to the guest for the bunk beds only.
Keep in mind there is a washer/dryer in our cabin also.
We raised foster children for 15+ years and so we really try to make it comfortable for families.
Good luck!
