We make sure we do something different each time we go! When we reflect back on our trips, we always refer to them by saying..." That was the trip that we tried..."
But to be more specific:
MK: Peter Pan's Flight and Wishes!!
(These 2 are my all time favorites. I told my DH that all I wanted for my 40th B-day this year was to go to MK, ride Peter Pan, and see Wishes.

And guess what? That's just what we're going to do.

)
Epcot: Me - Soarin; DH and 2DS's -Mission Space; Family - Trying all the different sodas from around the world at the Refreshment center.
DHS - RNR and Fantasmic
Boardwalk - Watching the street performers in the evenings.
And last but not least... My family will tell you that I
must always cry when I walk into Magic Kingdom. I can't help it. I just love, love, love to see my kids and all the other children's faces light up when they walk in the gates. It's overwhelming.
