Can't say I'm surprised about the lack of buzz, while the motion sickness issues can certainly be a factor, the literal buzzkill is the combo of Boarding Groups and Park Reservations. Not everyone wants to dedicate their morning/day at Epcot for the chance of getting on one ride, and that's one of the only ways you can get on it. Individual Lightning Lane is normally snatched up by resort guests, so you're out of luck their if you're local or staying off-site. And the third option of the Extra Magic Hours is for Deluxe Resort Guests only. It's really hard to create a buzz when there's so many limitations to get to it, and folks don't wanna' deal with that.
I'll be down there in a couple weeks, and I only have Epcot planned for one day. So I hope to heck I can get both an Individual Lightning Lane and a Boarding Group from the 1pm drop.
