Only if you plan on using
Genie+ or trying to join the 7am Virtual Que for Guardians at Epcot. The system will think you are starting at Magic Kingdom and won't let you book anything before 2:00pm. At least that's what happened last time during the Guardians preview and we had to visit the blue umbrella every time to book a Genie+
lightning lane which was a major hassle. I've emailed them asking if this glitch is fixed and no response so I'm not counting on it being fixed but perhaps if others called / emailed asking about it they would find a way to solve it.
