Well, if you are going to do the Monorail resorts...
Contemporary: At the Outer Rim they make a drink called (I believe) the Monorail Yellow, which was very good. Can't remember what was in it.....
Polynesian: Lapu Lapu or a Backscratcher from the Tambu Lounge
Grand Floridian: (you've dressed well, right??): Head into the bar at Citrico's for one of their Citrus infused martinis or Cosmos. They have great martinis.
Wilderness Lodge: Territory Lounge as some pretty good microbrews to choose from.
Now, if you're really ambitious...
Yacht Club: One of my favorite lounges in all of WDW! Try their Catcus Pear Cosmo
Beach Club: Martha's Vinyard-- good wine selection, but try their Oreo-Mintini or Hot Apple Morgan. Also, the pool bar at Stormalong bay has great drinks.... esp the Stormalong. A PIna Colada with Bailey's and Amaretto.
Boardwalk: TONS of choices, but head to the Bellvue Room. they specialize in single-malt scotch. Great Selection.
Swan/Dolphin: Feeling Exotic?? Kimono's in the Swan has awesome sushi and warm sake.
Still Standing??
Animal Kingdom Lodge: Victoria Falls Lounge has a good wine selection. Try a glass of South African Chardonnay.
Port Orleans: Toast the sunrise with the (incredible) Bloody Mary at the River Roost lounge at Riverside.
How did I do?
