Depending on the hotel you are staying at they may have a crib you can use. Call the hotel today and see what they have. It may not be hers but if you take her blankets and her stuff to put in it it may work for the trip. Maybe you could see if she will sleep on the mattress by itself on the floor and take it if you have the room(I don't know how you are traveling or if this is possible). Hope this helps!!
