I called the hotel ahead for this same reason they have plenty of pack and play cribs on hand.
Per the website they offer cribs and high chairs. Because of Legoland I think they are a very child friendly hotel. Also, request an accessible room. You will have more space for the crib.
If you go to their website it will list the room amenities.
