we have tickets on fridday night @ 10p

what is a good time to start lining up to not be seated late?

I got there early before they let people in because i had to pick up the tickets from will call. I probably sat down 30 mins before the show and was entertained by the clowns (I was in the first row so they messed with me). I don't remember much of a wait to be seated and then once in, you can come and go as you please (bathroom, concession)
"O" was awesome, the best show me and my girl friend ever saw! Enjoy

Went to O in feb, I think we got there around 30 minutes before the show started and got in no problem. Leaving the theater took about 30 minutes though as the doorway was super crowded.

The show itself is amazing, never thought Id like a Cirque show but this keep me entertained the entire time. Incredible.

EDIT: Just noticed you went to the show a couple days ago... so my post likely wasnt very helpful :)
