Thank you so much for all the amazing advice and info!! While I'm there they aren't doing Fantasmic or WOC =(If you split Hotels, you are eligible for 2 different programs.
The basic one is a "Magic Morning" with a 3 Day Parkhopper.
This gets you into Disneyland Park one morning 1 hour early. The Barcode tracks your one Early Entry.
As for the Three Disney Hotels, once again, you are NOT at WDW.
The Hotel program is one hour early at either the Disneyland Park (where you share the park with the Magic Morning Guests or DCA.
To access the "Extra Magic Hour", you show your room key at the turnstiles. Save your Room Key to prove you have a standard Magic Morning left after checking out. *The CMs know the issue, and will override the computer, since the Barcode will track your first DL early entry).
You can check-in the morning of your first date extra early, where they will process your info, and issue you the room keys, which are printed with your name and dates of stay. The type of admission doesn't matter.
I hate the process of checking in and out of Hotels, so honestly, I would stay at the Springhill Suites for the entire stay, use the one Magic Morning that comes with your ParkHopper, get MaxPass for all three days, using the savings from not staying in the Disney owned hotels, and enjoy the fireworks and World of Color performances from the rooftop pool area at the Springhill.
