The smell stepping off of the plane at MCO is what first gets me int he mood. We always arrive at night so that gets the excitement started.
The smell of AK in the morning is the best! We always starts off our trip there.
Also, the smell inside Space mountain, and Haunted Mansion.
The smell of the monorail.
The smell of beer in Canada since that is the first country we visit to start our leisurely stroll through the World.
Also, the smell of the basement of Tower of Terror while waiting to board.
Oh, I want to be there right now.
