When I visit the parks solo, my favorite Disney attraction/attractions would have to be the pavilions in the World Showcase at EPCOT. When I was working as a full-time CM, I would go to EPCOT on my days off and go shopping around the world. It is so relaxing to spend an afternoon by yourself taking time at each pavilion to see the shows and the shops and chat with the internaional cast. *sigh* Only 2 months more to go!
When it comes to actual rides, I love love love Test Track! I'll ride that sucker 4 times in a row if they let me!
For pure enjoyment, drinking around the world, hehe.
At DL, let's say Soarin after wine tasting!
and while we're on that train of thought...at DL, the Jungle Cruise AFTER chai martinis at the Uva Bar! One time the skipper let me drive...big, big, mistake...
Although, the old 20,000 Leagues Under the Sea... *sigh*. I used to get nervous on that when I was a wee lad (will the windows be able to withstand the pressure?!) lol!
