Whatever you do make sure you bring your own change. I put $20 in the coin machine on May 1, 2012 and only got $4.25 back. The machine ran out of money and there was no attendant on duty. They have a black box in the back where you could put in for a refunds request and I put my business card in there with a message about them contacting me to refund me for what I lost in the machine. It is now May 9, 2012 and I have yet to get a return call about my refund.
