Who cares about food, where is the best DRINKS in Disney World!?!?

Its me and my GF only going to WDW in JAN. We are mid 20's and are more excited about resort hopping, dining, and the whole disney scene than the actual rides.

I have 3 questions/recommandation requests

1 Where is your favorite bar in Disney?

2 What is your MUST HAVE alcoholic drink at Disney?

3 Where are the cheapest drinks?
