I got in on this too, though my reservations aren't until the end of May/start of June. Got confirmation e-mails, lots of screenprints, and tried calling and e-mailing Expedia to get them to personally confirm it. When I called (which was while their site was down), they said they couldn't look up any hotel reservations because the portion of their system that deals with hotels was down for "upgrades."

Anyway, I'd read elsewhere regarding the Expedia/Hilton debacle and saw mention that in that situation, they seemed to be more likely to honor reservations of people that called/e-mailed to confirm their itinerary. Thought it was worth a shot.

Currently, my reservations are still showing as active. Hopefully, they'll stay that way!
