Jennifer,
Boy that is a tough one. The good news is that you will have fun with whatever plan you go with, so you are in a win-win situation!
For me, it would be the
Hoop-Dee-Doo Review. Even thought it is expensive, and despite the fact that I am a fan of the House of Blues, I think that the Review is a better choice. Why?
First, there are House of Blues elsewhere in the United States, so you might actually have a chance of getting that experience elsewhere. There is only one Hoop Dee Doo Review.
Second, while the House of Blues Sunday Gospel Brunch is a great experience, you are just there for a regular dinner, not an entertainment experience.
Finally, Hoop Dee Doo Review, despite being expensive and a bit corny, is a Walt Disney World experience you just have to have! For my wife, it is her single most vivid image from her first visit as a 6-year old. The food is decent, the fun is ideal for your family, and you will never forget it.
I hope that has helped.
Have a magical (and delicious) vacation!
