Hands down, if it is open Mickey's BBQ
It is a few hours long and a whole show, dancing, screaming kids it is the best.
You also get free beer, a night out, GOOD BBQ food. Icecream after dancing for 3 hours. And Mickey Mouse.
This is IDEAL for ages 4 and 7. And did I say beer and tip is included.
It doesn't run in winter.
So in winter if they are girls I would go for CRT, as although the food isn't super great, you get a free picture package and the FGM or princesses depending on when you go is great. Although it is not my Fav, this is all my DD5s fav. She talks about how she had dinner in the fancy castle, and saw the FGM.
