I have researched the all-inclusives and 7 cruises. I just got back from a 5 day cruise and with the cost of the cruise I spent at least $1000-$1500 less than an all-inclusive would have cost me. Most of the "hidden cost" is drinks. but a good reference is what mike said $100 day. and if your a beer drinker like me you would spend $500 an 50 beers on your cruise. just a reference!
