I highly suggest you try it. I've been once and hopefully will be back this year.
Quoted from PW79:Do I get to play spectator games too or am I in tourney play all day?
You pretty much play all day. There are some breaks, but it's an all day event.
Quoted from PW79:Anyone else go?
Yes
Quoted from PW79:If I attend as a spectator I can't play the tourney titles right?
Not unless you stick around for the finals and / or the after party (which is usually worth the trip)
Quoted from PW79:If I play poorly am I out day one (AKA how many days/nights do I book)?
No. You get 2 full days of playing regardless of how bad I sucked, I mean, regardless of your ability. Then you either make the cut, or, like me, play in a separate tournament on Sunday for all the "did not qualify" people.
Quoted from PW79:When do they open/close the doors each day/night?
Depends. I think we started at 10 or 11AM and played for about 10 hours. They may change the closing, but I think it is around midnight.
Quoted from PW79:Any cool places my wife can go during the event (besides your hotel rooms lol)
Have no idea. After 10 hours of pinball, it was time for beer and sleep
