We went once in November, it was okay. I thought the show was super boring until close to the last 20 minutes. We had tier 3 seating and it was hard to hear, we weren't really facing the stage, I had to turn my head and neck all the way to the right to see anything, which is awkward when having dinner with others and eating.
Food was okay. The dessert was good and the sangria was drinkable.
Price, pretty expensive, we used a Tables in Wonderland discount, but it was still about $60 per person I guess.
It does include house wine and sangria (think cheaper sangria that comes from the bottle) and beer (like Budweiser).
I probably wouldn't go again.
BUT, this is one of those things that I think most people should try for themselves, as most Disney experiences, your mileage may vary.
