What time are you taking the wagon ride? The Chip & Dale show before the movie at the Meadows starts at 7.
You can get pizza, the Giddyup and Go chicken bucket or lots of other take-out at Trail's to Go, it usually takes about a half hour to get your food. They will give you a buzzer and you pick it up when ready. The entrance to the take-out is between Pioneer Hall and the Trail's End/Crockett's Tavern entrance. There are picnic tables on the porch or there are a ton of tables around the marina where you can sit and eat.
You can sit inside at Crockett's Tavern if it's not real busy at a table and get food brought to you. We got pizza and nachos one night from the bartender, but like I said, that's usually only if you go right at 5 pm and ask nicely.
Trail's End is a great buffet and we go there every trip. Fried and baked chicken, ribs, chili, carved meats and the best cornbread on property. Also the lowest priced buffet on property.
You can watch Wishes from the beach and Electrical Water Pageant comes by at 9:45 if you're planning to make a night of it.
