In a lot of ways, asking the question on a Disney planning board skews your answer. We usually have several years between trips, so when I’m not actively planning a trip I let my TP subscription lapse and don’t spend much time here in the forums. (I’d find it depressing to spend this much time reading and thinking about Disney knowing it would be years before I’d be back.)
But back to the question…we plan our trips based more on our schedule, preferences, and finances than any specific thing opening at Disney. We’ll be there in early November. That trip was planned a year ago, back when we thought GE wouldn’t be open this early. We didn’t even consider delaying it until new things opened–our trips there are infrequent enough that we’ve only ridden most rides once or twice; there’s plenty for us to do without new attractions.
After this trip it will be a while until we’re back. It’s a combination of rising prices and crowds (especially during the school break weeks when we can take vacations), my oldest not liking Disney much anymore, and wanting our kids to see more of the world than just Disney. We’ll be back, but it won’t be tied into anything happening/opening at Disney. No, that’s not true–massive discounts would get us back a lot faster!
