While I have not stayed at OKW, I have stayed at other resorts. The way it has worked is that they will have a campfire on particular days (you'll have to see the resort schedule to verify which days). And they will provide, free of charge, marshmallows and sticks for roasting. But if you want to make s'mores, you will have to bring your own s'more supply, or you can purchase a s'more kit at the campfire. Hope that helps!
