Maybe it's the upstate NY redneck in me, but I'd be happy if they had big tubs filled with cans of soda and beer on ice for free, and then have a bar for discounted mixed drinks and wine.
Now Dave you know that would never work. I can just see one person walking up and taking six beers at once. The same reason they don't have open bar on cruises-to-nowhere anymore. My first 1nt CTN on the Fascination in 1999 was open bar. The bars were swarmed with people and you waited forever in line to get a drink.
