Okay, we are in the minority, but most of my family hates it. I have to say that we all went when the kids were young and we all enjoyed it. My DD as been "dragged" to it a few times as a young adult when she wnt with her aunt, and so when I booked it 2 years ago, she and her DH refused to join us. My DH, my 11 DGD and I went and there was mixed reviews. My DH laughed so hard through the entire thing. He loved every minute, the food, the food the food, the show and the server. I liked it, but thought the humor was cheesy, which was part of the charm. I liked dinner. My DGD was hysterical! She did not like the show, not one bit. She did enjoy watching her Pa. I really think she had more fun enjoying him enjoying himself, and so the evening was a success.
I think that there are 2 dinner shows that are classic Disney, and the HDDR is one of those two. I do not think you will go wrong going to the show, and I do think your family will enjoy it, even if someenjoy it for different reasons than were your intentions. LOL! If you want to stretch the evening, think about taking a wagon ride around FW. We did this after HDDR to see the Holiday decorations throughout the campgrounds.
