We had a similar experience last Oct. We went with my Mom and my Sister and her family. I have 2 kids.. they were 6 and 10 at the time. Now I am not saying my kids are perfect.. but they are their best in Disney. They mind and have a great time. But my Sister's son who was almost 7 at the time.. He was AWFUL. He pitched a fit about everything! He hit his Mom .. His Dad and My Mom during the trip.. He pitched a huge fit one day and broke the table in the hotel room! He has since calmed down his anger some.. But the trip was hard because of it. We tried to distance ourselves some from them and we ended up having a great trip.. But to make it worse not too long ago she said we needed to stay together more the next trip because she thought that her son had acted up so much because my kids were not with him enough. Blame my kids!
