I sure hope Ragu is right about plans to keep COP and Timekeeper open while they redo AE. Those two rides have been closed every time we've been to WDW, and I was really doubting that we'd ever get to ride either one. But if they keep them open while AE is revamped, and AE will be closed about a year, then that means COP and Timekeeper would be open for our trip in June. Woo hoo!!
As far as the original topic of this thread goes, our family rode AE once, thought it was OK, but never planned to ride it again. We all love Stitch, and I think the revamp is an excellent idea.
