On the timing of the rehab, I can see why summer would seem a crazy time to do it -- but as PP alluded, summer has advantages for WDW to manage flow due to the parks being open so much later than in other seasons. It is typical to have MK open until midnight in the summer -- but often only in the 7-10pm range in fall and winter. While there are tons more people, particularly in the heat of the day, the longer park hours help spread it out, and spread people around. Plus, given the confines of the time space continuum, they have to do it sometime -- inevitably making someone unhappy. Unlike 10 years ago, at least you will now have EE and RnR for coaster action while Space is down. Not the same, but some consolation.
