I'm one of those who also just thinks it's just okay. Our family of 4 went in Dec. 2003 and we had just a so-so time. Granted, my 4 yr. old thought the jokes were very funny, but, to me, not so much. Very corny, but then that's what I expected. I think for me the biggest disappoints were twofold:
1) Even though the room was no where near sold-out, the tables they did seat where still so packed together that it was hard for the performers to work through. I can only imagine how tight it is in more crowded times. When we were there only about 1/3 of the lower floor was being used.
2) The food was mostly okay. Biggest disappointment was the chicken. It was okay, not great, and barely warm. When we did get a few more pieces from the kitchen, it was hotter, and definitely better.

Lesson learned-if you don't like the tempature of the food, as for more.
Additional, I didn't like the fact that we were supposed to arrive so early and all we could do was stand around outside (early Dec-it was cold!) and wait to be admitted. The only thing to do was check out the jewelry for sell, visit with the horse (wagon rides for sale), or sit on the porch of Trails End Buffet if you could get one of the highy coveted rockers.
The performers were good, but IMHO, the food and show wasn't worth the price. It should be noted here that we were traveling with my niece who was a DL employee so we got a discount and I still thought the cost was too high.
So, these are my 2 cents, HTH
