We had free breakfast and that helpd alot with 2 teenage boys. We'd grab a quick patty at CoCo's for about $1.80 each....drinks and dinner would run us $80-$100 at nice places. We bought a bottle for cocktails in the room...that saved us ALOT. Even though we're not big drinkers, 2 or 3 each adds up. You can certainly do dinners for a lot less, like a pizza, or something from a cart, but we didn't do that. I would say $100 would be a safe bet. But my kids are 15 and 13 and have very expensive tastes....you can probably get your kids to order off the kids menu and that would save you also. Go enjoy and have fun!
