Day 0 Thursday which this year is Oct 26th, day 1 Friday the 27, day 2 Saturday the 28, day 3 Sunday the 29th the last day of the con. Hope that helps. Last year my group got to pre reg at like 3 pm, no line and no one really hanging around. Not sure where everyone goes for day 0 fun, but we went to Ground Kontrol, was fun. Any other questions about last year and I will try to help.
