I dunno- I think I ate/drank $100 per day. If you think about it- our resort had pricings on their buffets (although I thought the only option was AI). Breakfast, lunch, dinnner, snacks, tons of drinks. It adds up and you EAT a ton more at an AI than you would if you were paying for it.
We spent $100 one night in a club on drinks. It went FAST too!
