I have tried it and for me it was a mixed experience. I did have a lot of fun, BUUUT...
I was hotboxin it in my car before I went in, and I kept thinking one of the parking attendants would see me, then I thought the security were staring in my eyes forever looking for redeye.. (Where I go they look through any bags or whatever trying to find weapons and such)... then in a queue where they had stairs going up and down the sole of my shoe fell off and I was sure the people around me could tell somehow that it was because I was high. So I was asking the ride attendants if they had any tape, and I thought they were looking at me strange. They directed me to the medical station, and I met one of the performers in there, whoo! She was absolutely delish. She told me she broke her finger during rehearsal, I told her about my need of tape, we hit it off really well which is odd for me I'm usually terrible with the ladies. She told me to come see her at the 5:00 show, she would be greeting people out front and after the show we could hang out in their break area. Anyways, by the time I went to the theatre all the tickets were gone, I was no longer high, and I didn't have balls anymore to just tell the door guy about it and try to get him to let me in. So that sucked. I should have brought more weed, although I worried that when they check for weapons they might find it.
