My kids aren't old enough for HP yet (I'll probably start reading it to the oldest in 5 years or so), but I'm a fan, so this tour was really fun! They control the # of people admitted per day to ensure it's never too crowded, there are lots of interactive and photo ops throughout. My son really loved the wand choreography especially, and my daughter liked riding on a broomstick with me. We arrived at 11:30 and went straight to the cafe for lunch -- this worked well, as we were all relaxed and energized for the tour! You do the tour at your own pace. We spent about 4 hours meandering among exhibits, doing activities, drinking butterbeer, etc. Loved it and recommend it for any HP fan, even if your kids aren't old enough for the movies or books yet!
