95% of the time, I find the 2nd F! show to be less crowded, meaning the typical recommendation to arrive 90-120 minutes early is not needed. We tend to wander over about 20-30 minutes before show time and have no trouble finding a seat. However, on very rare occasions, the first show has been cancelled for rain/tech difficulties, meaning the 2nd show is the only show. This is a bad, bad thing. You should go back to the hotel.
