Went to Flamingo Hotel recently and try the 20$ trick with success ! I put my twenty dollars between my licence driver and credit card and ask for a complimentary upgrade room. The woman clerk refuse my 20$ but change my standard room third floor to another standard room in the 26 floor with a perfect view of the Caesar Palace and the strip ! I was very nice with her, polite, and I think my french accent helped me a lot. Even if she refuse my 20$, I put it on is desk and immediately leave after. She left a message on my room voice mail saying that she hope I'll enjoy my stay in Las Vegas and to not hesitate if I need anything. Simply perfect !
