We just got back from the 4 day Wonder (5/4/03). We took all three of our children (ages:5, 2 1/2, 1). Our 1 year old was quite difficult on the trip....especially the first night. She did fine during the breakfasts and lunches, but at dinner time, she was a TERROR. She also wasn't fond of sleeping in the pack 'n play. Every child is different, so I don't mean to scare you. I wish we would have waited another 2-3 years to go.
