I was an annual pass holder at Disney World (unlimited access to any park any time) for 20+ years. Hands down Epcot was the park my family & I spent the most time in. I have the "pub crawl" route in the World Showcase down (no alcohol served in Future World).
My preference - turn right and go around the lake counterclockwise. Go cups are served.
Stop at Canada for a Canadian beer (start light). Or you can go with Unibroue heavies.
Wander on down to United Kingdom for a black and tan (or two).
Cross the bridge and visit France (wine stop for da wife) French beer sometimes available.
Stop at Japan in the sake bar (very nice selections) and the tempura bar and/or sushi restaurant Japanese beers available there too. (this is the best spot to watch fireworks from)
Continue on to the American Experience for a turkey drumstick and a Samuel Adams
Then, destination achieved, Germany. The bier selection here varies with the season. There is always a seasonal bier on tap (along with one or two others) at Germany. Highly recommend the goulash soup and soft pretzels. The bratwurst is very good too. If you want to have dinner in the Bierhall the buffet food is very traditional German fare and quite good, and they have an extensive selection of bottled bier and wine to choose from. Germany is the 2nd best spot for fireworks. The fireworks happen over the lake. Hot tip: don't watch fireworks on the downwind side of the lake.
If you're still up for it, there are Chinese beers at China and Mexican beers at Mexico. Margaritas available at Mexico.
I usually don't get past Germany.
The beverage selections vary throughout the World Showcase constantly. The best time to visit (all times are good), hands down, is during the Epcot Food and Wine Festival in the fall. In addition to the mainstay countries' pavilions, they set up many food and beverage stands throughout the whole World Showcase, and have many special tastings and dinners.
Next to watching launches from the Cape in person, I miss pub-crawling at Epcot most, since I moved to Hawaii.
