I saw that too. We're family friendly, but don't provide all, or even half of the items on that list. Parents used to travel with their own "pack n play" travel crib and other things for their little ones. We've noticed an increase in the number of people who ask, or even expect, us to provide a travel crib. Although travel cribs don't cost that much, there's extra work involved in setting up, taking down, and cleaning a travel crib. Not to mention the additional liability if something happened to the child while using our equipment.
We would incur extra cost and extra work if we provided the items on the family amenities list. And infants/toddlers aren't even covered now in the guest count! We're starting to feel uncomfortable about even listing our place as family friendly if parents expect us to be equipped in this way. In a way, Airbnb is raising the expectations of the guests. Has the hotel industry already set this as a precent?
