I was in Vegas for the very first time for the SEMA convention in November. I wanted to stay one more night in Vegas so I chose Paris due to their fun theme and rates for the night I needed. I remembered reading here about the $20 trick so I decided to try it. But I forgot to fold it into a sandwich when I approached the desk. Instead, I held my wallet open in one hand and had my other reaching in, as if I was ready to pull out money. I asked the lady if there were any complimentary upgrades available, and I said it with a goofy grin - as if to imply that I knew she gets asked that a million times a day. She started typing away and said, "hmmm let me see..." I then told her that I was a big fan of jetted tubs... which I am, but what the heck, it was worth a shot. After a few more seconds, she looked up at me and said, "okay, it's all yours!" Stunned and surprised, I reached into my wallet and handed her a $20. She was very appreciative and so was I. The room she gave me was a gigantic suite that had two bathrooms, about 1000 sq. ft. and by far the largest room I've ever stayed in. What a great way to end my first visit ever to Vegas. I've been doing the $20 trick ever since.
