let's just say you can't find a ressie for BOG...if it were me, I would rather eat at a monorail resort. I have tried CRT- meh , overpriced. Tony's- it was okay, not bad. LTT..same. Nothing to really write home about in MK other than BOG IMHO.
I would try for Ohana's at the Poly which I bet your whole family will love, Chef Mickey's in CR or for a nice dinner, Narcoose's in GF.
If you must stay in MK my best option is the buffet in Crystal Palace.
