I've taken kids to both Hollywood and Vine, and Mamma Melrose - H&V is the way to go. Didn't want to use extra ts for Brown Derby for a meal that wouldn't be enjoyed (2 small kids = 'n' trips to bathroom, knocked over drinks, and adults eating a cold meal; no matter how well-behaved my precious angels are).
I'd highly recommend the Fantasmic! dinner pkg, though - the seats give you a great view (I don't think it's possible to have a bad seat in there) and you can sit right up front if you want (on right hand side, but still). It certainly beats lining up with crowds to go early - even 1/2 hour before show (which I think is last time they recommend you go with pkg) is a long wait with toddlers. The wave can entertain you for only so long...
