I also had a great time!
In terms of the Celebration store, on Thursday, they opened early for VIPs, but it was a total disaster, as their terminals kept having problems connecting through the wi-fi, and then it turned out that many product sku's had not been loaded into the system, so the entire system was closed down for over an hour while people just waited in line. It wouldn't have been so bad if the line had been moving, but it was actually entirely shut down for a long time. Many people left instead of waiting. Most VIPs were there for more than 3 hours. As for the regular attendees, some waiting for over 5 hours, and the line was eventually capped.
After the first couple days, and once things started selling out, the line became much more manageable.
