While I love all the parks for different reasons, MK is truly my favorite. Especially at night. Plus, the HM is there and I make it a point to ride it at least once a day every day that I am at WDW (or, as many times as I can get away with it before DH says "okay, time to ride something else). :lol:
I love the parades, the fireworks, the rides, the lands, Main Street, the castle, the CMs, the music.... just total love for the place.
