Magic Kingdom
Days one though three: Run furiously from FP ride attraction to FP ride attraction. Eat at walk-ups for lunch and dinner. Stay for fireworks.
Day four: Skip the rides. Walk through the shops on Main Street.
Look up at the 2nd and 3rd floor windows. Take pictures of them (you can search for the backgound stories of those names later, too).
Stroll through the other Lands and just "be there...in the moment".
Make believe that you are in the future or are in a real frontier town, or on a African safari or in a N African bazaar.
Again...look up and around you. Disney has put incredible details into everything, so take the time to enjoy them.
(okay - look for Hidden Mickeys, too)
Stop to listen to any street performers.
Engage the Cast Members (to the degree that they may be able to, given their job). Check out their name tag which includes their hometown.
Take pictures of various details. Light fixtures, trash cans, pictures, and other small detail which most frantic guests miss.
Listen to the music that accompanies almost every square inch of the Park. (Such as the Jungle Cruise queue).
Day five and six: Take the Monorail from TTC to the Polynesian Resort, Grand Floridian and Contemporary. Walk around each one.
Catch the bus from MK to Animal Kingdom Lodge. Walk through the amazing lobby to the savanna view areas.
Then, take take the bus back to MK and catch the boat from MK to Wilderness Lodge and walk around it as well.
Day seven: Go to Disney Spring and buy the stuff that you didn't get during the previous days.
Then...start dreaming about your next visit.
