My family and I will be travelling to Pittsburgh from December 17 - 20. We have 2 children ages 7 and 4 and are planning on going to the Zoo, Carnegie museum. I am looking for suggestions on hotels, specifically one with a waterside. Does anybody have any suggestions on where to stay? We will be renting a car so while I would like it to be near these attractions I would be willing to stay a little farther away if it had a waterslide.
