I called MS, trying to get some additional information about this event. I'm was trying to convince DH to take a few days off for this before he goes to work overseas for the summer and some of the information seemed rather vague to me.
CM told me that the viewing location in Epcot has "not been specified" but will probably be near Future World as that is where the party will be after illuminations (my guess is probably the large patio area where the characters do meet and greets) - only Mission Space and Test Track and that area of the park will be open during the party and the rest of the night.
On MK night you would view Wishes with everyone else before the park closes and receive a voucher for a "quick and casual" meal (counter service). When I asked what attractions would be open she said they were being told it was "not specified", but "like an e-ride night" - it would definitely include Philharmagic. And, of course, the private showing of Spectromagic.
She said times for SSR event were not yet set "probably something like 10-2" and when I asked if the lunch would be a buffet she said they were "not sure yet."
She said yes, transportation would be provided to all resorts after the events (I specifically asked about the monorail).
DVC rooms are apparently sold out - no studios anywhere, 2 2 bedrooms for 2 of the nights at OKW and a 1 bedroom at boardwalk for Weds night. I'd think the Contemporary would be a good central place to be.
If this were one week earlier and not so stressful for DH to go the week before he leaves (I know he would go for me, but I don't want to stress him out), I would probably spend what seems like too much $$ for what they are offering - I hope to hear reports that there's a lot of great "extras" they are not mentioning for that price. I have to admit that I'm surprised that they are so vague and noncommital about what they are offering this close to the event. I can't wait to hear that it's a wonderful time and hope that the next time they do this they give us more advance notice - we did not receive the first invitation even though we've been members since last Aug - just received one recently - maybe next time

- wish I could be at the Dis meet ! - have fun everyone !
Mark - great links - how nice of you to organize the meet for everyone!
