My husband and I and our boys (4,10, and 12) are going to Disney for 11 days but for one day we are going to Universal to see the new Harry Potter. I have two questions.

1. Has anyone done the kid swap for the Harry Potter castle yet? How did it work? How was your experience?

2. I noticed that the day we planned to go to Universal is one of the nights of the Halloween Party. We do not plan on attending it. Should we go a different day because it might be more crowded because of the HHN?
