We stayed at the Courtyard Marriott. I have to say that there was very little chaos in the halls. Upon check in I had to sign a piece of paper stating that I would be responsible for my (4) kids behavior while they were in the hotel. The agreement specifically stated what was expected from the kids AND parents.
Other than the kids who were playing hide and seek in the hallways - and that was early and you have to be very quiet playing hide and seek in the hallways!! - the kids and parents were very well mannered. So, I guess my friend totally scored when she made our reservations!
