We love the Hoop Dee Doo Review. I have been with my family when my kids were young, now with DS and his children at about those ages and also with all adults. We had a blast each time.
DGS about age 4 was chosen to go on stage as part of the show. It was priceless.
It is a western themed show with singing, dancing and corny jokes. The performers come out into the audience and there is audience participation. It is lively and tons of fun.
The food is "down home cooking" with Fried Chicken, Ribs, salad, corn bread, mashed potates and beans. It is served family style in "buckets" and it is all you care to eat. Dessert is a delicious Strawberry Shortcake. We love the food. There is also beer, wine and sangria included for the adults.
We think the show is a hoot, and the food is very good. It is well worth it and I think your children are the perfect age.
As a PP suggested, I would take a rest break in the afternoon before the dinner so you little ones are rested and can have a ball.
Enjoy
