The HDD is a great show to take the kids to!!! Our 6 yr old DD had a ball!!! The jokes are soooo corny, but if your kids are like mine and tell the same knock knock jokes, and make up there own jokes that only they get you will have a ball!!!
Yes it is expensive...it was $120 for the three of us. But we found that as with all the dinner shows/extra entertainmetn at WDW it was well worth it. The food was good (Loved the chicken) and it was something new and exciting. We had the 7:15 seating, but there was one in front of us and one at 9:30 also. (We were there July 8 for dinner).
We orginally made our PS way back in the spring, but the last week we decided to do some changing around of our game plan. We were flexible as to what day we wanted during our trip, but when it came down to it we were able to get a seating on any of the days we were thnking about. the 7:15 show had the most openings. Afterwards you can walk to the beach and see the Light Parade on the water!!! This is really neat.
My advise....plan enough traveling time or drive to Fort Wilderness. We stayed at WL so we were close but I heard many people talking about how long it took to get there. The bus system leaving is very confusing...Two buses stop at nearly the same place, but one is going "in" and one is going "out". Mark the bus driver is the only one that "knows what's going on!!!" All the other drivers were VERY confused!!! This is the only place where we had trouble with the bus system, but i think it is just because there are so many different people coming and going from it, and there are only the two very confusing ques for the buses.
AlL in all it was a great time!!!
