We're not going to
MNSSHP. It seems too early in September to go to a Halloween Party. I'm going the week after Labor Day. Planning was a little bit difficult as we hit two hard ticketed events, Night of Joy and MNSSHP (which moved around on the calendar).
My little one is now ten and 5'2" and not so little anymore.
For us the best thing when my son was younger was the buffets. Kids can have their pick from the standard kids foods or real foods. Plus they get entertained by the characters. The food at Crystal Palace is decent and Chef Mickey's really isn't that bad. My DS loves the Mickey Ravioli there. Tusker House at AK isn't a character meal for lunch and dinner, but they have mini-corn dogs and a DIY PB&J bar for some variety. At Epcot, Garden Grill is entertaining with the characters & rotating restaurant. But my son has always loved the cheese soup & breadsticks at LeCellier. (If you can get a coveted reservation)
However, we hated Hollywood & Vine at DHS. The only thing I liked there was the beet salad. Never ever eat multiple servings of beet salad, you might think you're dying the next day.

50's Prime Time cafe is fun and lets the kids have half portions of meat loaf & fried chicken if you're looking for something besides standard kids meals.
Next year, if MNSSHP is on Saturdays like this year, I'm thinking about going when we get back from the cruise.
