We did it about 2 years ago and wouldn't do it again. Some people on here have posted about having a wonderful time great Cast member and all. But our cast member wasn't exciting didnt' get the group involved and we just seemed to walk through the park. Then at the end we got a private greeting with Aladin. That was it! We had free passes for this I would have been very upset had I paid all of that money. Other people posted that the character they met took them to the front of the line for a ride. Not us! I guess we were a group of about 12 with kids. we did get to see some hidden mickey's and some interesting information.
Hopefully others who had positive experiences can give you a better picture.
Have you thought about the pirate cruise? That sounds like fun for the kids
