Ok having experienced DATW a few times let's see if we can clear up some misconceptions.
There have been some DATW's where the goal actually WAS to have a drink in every country. It was soon discovered that was really kind of difficult to accomplish AND suceeding in that made one completely and utterly smashed.
TRUST me on this
Since then it has morphed into more of a nice walk around epcot with people stopping for the occasional drink.
People bring kids, everyone is friendly and generally it's a pretty good time.
You don't even have to stay for the whole thing, make a few stops and if your not having fun, move on, nobody will care
Just have fun!
