We love it. When I was planning our upcoming June trip, I asked DD9 (who was then 8) if there was any particular restaurant or, specifically character meal she wanted to go to. She immediately said HDDR. DS14 likes the show a lot too.
Also, it gives you a chance to go to Fort Wilderness and look around before or after the meal. There is a gift shop across from Pioneer Hall that has stuff you might not find at other shops. DMiL found a bag that she had wanted (a friend had come back with one from WDW) but was sold out at the Main Street Emporium when our trip came around. The shop at FW had a bunch of them.
