whats the best time to go? also groupon only has adult tickets not children ...

I went at night and its not busy at all and if you have a student id you get $5 off

I went on a Wednesday around 1pm and there weren't that many people. Kids from 5 to 12 yrs old are only $10 at the door. 4 and below are free.

I went on a weekend around 8p.m. I didn't do the Groupon thing so I don't know about that
