Well, the top attractions at the parks was a good thread and all and there was some good discussions on rides that some love/hate and rides that used to be good and have declined. However, let's be more specific for fun. I know it is hard, but try to narrow it down to just 1 attraction out of all 4 parks that is your utmost favorite, and you wouldn't miss it if you went to Disney World. Yes, I am asking you to pick one total attraction that is the best at WDW, so you will have to compare attractions from different parks say Tower of Terror verses haunted Mansion verses Expedition Everest.
I really don't have an opinion here :-P! At DL, I would probably say Pirates of the Caribbean. At WDW, I don't really remember liking one particular ride a ton more than the others. Maybe I would say, Space Mountain.
O yes, you can defend your choice and why it is your favorite choice too.
Also, pick the worst attraction in the parks in your opinion. You can defend that one too as I'm sure there will be some debate on it!
