Our first & last Park of each vacation is always Epcot.
For us, that's the "Heart" of Walt Disney World.......much like the Magic Kingdom is to so many others
We live in Southern California and have been visiting Disneyland all our lives, so we view the MK as a slightly different, but wonderful version of DL.
Epcot, on the other hand, is a totally unique experience, and the only way to begin & end our WDW Adventures.
