I bought my all day pass at Tix 4 Tonight for $20 instead of the regular $35, and this was a plus. Playing for several hours as much as I wanted was definitely worth the $20 that I spent.
That said, I would never go back. The entire time I was there, the place smelled awful, almost as if the bathroom had exploded and there was sewage all over the place. In response to this, the management decided to just spray bathroom spray to try to cover up the stench. Unfortunately, the management didn't realize that you shouldn't spray aerosol in somewhat enclosed areas without proper ventilation.
The management seemed ambivalent to this and said there was nothing they could do about the odor besides spray to try to cover it up.
Conclusion: Don't pay full price for the all-day pass. Bring your own bathroom spray.
