There is no food court at OKW. There is just a small counter service, really small, at the pool where you sit at picnic table outside to eat. There is an even smaller counter service at the Turtle Pond pool, The Turtle Shack, and that is only open seasonally and usually has short hours.
As for booking a GV at seven months out, I was able to add one night to a five night stay for late May/early June several years ago, but it could be hard to book the entire stay at seven months out. Especially for a holiday week (MLK weekend) and the least number of points required than every other GV. The GV will have one bedroom upstairs with two double beds in it and the other one upstairs will have two queen beds. The one with double beds is rather small and two queens would never fit in it. Getting a studio and a two bedroom might be easier to book.
