We have done the world showcase "booze-tour"

a few times... (too many)
Here is my World Showcase touring/beverage plan:
Canada - We always start in Canada and have a few beers. Moosehead & LaBatts. I tried this Bloody-Mary type drink with Clamato once (Don't try this one on the one day tour), but mostly beer.
UK - Guinness is a must, even for non-beer lovers. Now, here's where I get myself in trouble. I know that I am only on stop 2 of 11, but Guinness is kind of like Lays Chips... I can't have just one. I down some fish & chips to tone down the Guinness
France - I'm not a wine drinker, but this is France after all. When you go into the little "Bakery" type place, ask them for the "house" wine, they gave us several glasses and it was pretty good.
Morocco - There was a Moroccan beer that was very good. I can't remember the name, but we had more than 1 and struck up a friendship with the guy serving... yes he was from Morocco.
Japan - Sake, Sake, Sake. I spent about 3 weeks in Japan when I was in college and fell in love with sake. Go to the lounge, get some snacks and sake. Hot or cold, sake is worth the hangover.
By this point you are feeling pretty good (we always are in control and most times have had a designated walker/tour guide to make sure everyone stays in control).
USA - Here we normally take a break. We have a few Sam Adams, then take a rest in American Adventure.
Italy - Here's where you separate the drinkers from the pretenders. The Bellini is a must. This is one of those drinks mom warned you about. It goes down smooth and you can't believe you are drinking alcohol. Don't get stuck here. This happened to us once and we woke up the next morning sleeping by the animatronic cave man in Spaceship Earth!
Germany - Back to beer. There are too many to try so just pick one or two and don't look back. Spaten Optimator is a fav, but experiment. Also, this place always seems like a giant

, maybe it's the fact we are all feeling good, but this is always a difficult place to leave.
China - We normally just get a Chinese wine (after German beer it would be unfair to drink beer from China). It is refreshing and gives you the "energy" to finish the tour. (Side note - at this point you should stay away from egg rolls, sauerkraut or any food from Norway unless you want to leave a giant sized mousekeeping envelop filled with "apology" bills the next day in your room.)
Norway - Carlsberg, enough said. I also agree with another poster. Ride the boat in Norway, trust me, you will think you are on Space Mtn with a "Where the Wild Things Are" theme!
Mexico - There is a reason why we end in Mexico. Canada really does not have a place to sit outside and drink. Grab a margarita and a table at the cantina and toast to a job well done.
I agree this is not for everyone and I don't think you have to drink to enjoy yourself. But if you enjoy a variety of adult beverages from different countries this is about the only place.
Enjoy!
