not to sound like the board's alcoholic but trust me when I say this...as I've done this quite a few times.
start off at Ohana bar (not sure about contemp and gf, tho if you can make it over to cali grill, they have some good stuff there)...have a few pina coladas, mai tais and whatever else you like.
head over to the monorail (be respectful, we can keep it in

)
goto MK
and ride space mountain as many times as possible...thunder mountain is quite a treat as well...if you want to be mean, get on the speedway
part 2
pick up your fastpasses from mission space or test track...go around the world (start at mexico, helloooo margaritas) and do all the countries. we don't go inside the restaurants, we just pick something up from the stands.
you can also check out on your lil journey, malestrom!, el rio de tiempo (a nice place to relax with your margarita), and journey into imagination. then go hit up the thrill rides!
its so much more fun...mission space will knock you off your feet, and test track is quite a treat.
we've done this a few times, but we're completely respectful, we dont go around being loud and obnoxious because I refuse to ruin other families' (especially with children) experience at the parks.
if you can keep it in, give it a try!
oh and as for drink prices, disney world has nothing compared to south beach prices...so its allll good
