Not sure on the change. They may be figuring for people working. I was hoping to get an earlier time so I could make it back across the bridge before 3 but got 230.
They do not put a limit on the number of seats you can add but have the right to limit it if they suspect you are adding just for resale. Guessing there will be some seats with nice equity after the massive rezone.
Personally will probably just skip the event, keep my purple 301's that are DEAD CENTER plus continue mgb's account for his widow. Will drop my pair of tan seats I had been using to upgrade.
