If getting up early will derail your feeling of being on vacation, don’t do it. Enjoying your own kind of vacation is the most important thing.
Otherwise ...
DO IT!!!
Getting some high-wait headliners out of the way early will free up time later to enjoy attractions that don’t have crazy long lines. Epcot probably isn’t all that advantageous to rope drop unless you have a big Frozen fan in your group, because most of the other wait times there are pretty short all day right now.
I rope dropped all the parks this week. Here are the attractions I was able to do with super short waits before official park opening:
Tuesday - MK: Peter Pan, BTMRR, Splash (Went to 7DMT first, but it was was having “technical difficulties” so I changed plans on the fly) Was also able to ride Pirates basically walk-on right after official park opening.
Wednesday - HS: MMRR, MFSR, Black Spire Outpost, then very short wait at TSMM right after official open.
Thursday - Epcot: Test Track (not sure that started running early, but rode with very little wait).
Friday (today) - AK: Flight of Passage and Navi River, then walked on Safari just after park open.
