I am taking my first trip to Walt Disney World in my adult life this January. The last time I was there I was perhaps about 10 years old. Epcot was still EPCOT Center and Communicore and Maelstrom made a huge impression on me. I cannot remember anything of the Magic Kingdom, which is probably because of my overabundance of Disneyland memories. We will have 7 days to visit all the parks and the various other attractions around the resort. My girlfriend is a Disneyland CM, so we will be using her sign-ins for entrance.
My questions to you are: Are the CM sign-ins parkhoppers or are they one park, one day tickets?
Any tips or tricks for some lesser known attractions/resort offerings?
What is the best order in which to experience the parks?
Any other information I can get from you all who know WDW better would be appreciated. Thanks in advance!
