Las Vegas: The $20 Tip

I don't know if it's a bribe or a tip, but I can personally attest that slipping the check-in representative a $20 bill (folded and handed to her when she asks for ID and credit card) and asking, "Are there any complimentary upgrades available?" really does work in Las Vegas. From everything that I've read, this is one of the few cities where this trick does work. I did it on a busy tourist weekend (July 4th, 2011) and got a smile and an "of course!" as a response. The $20 bill disappeared and I had the choice of whether or not to stay in The Venetian as I previously booked or move to the quieter Venezia Tower (warning, there is no WiFi there) or to the even more luxurious Palazzo. We ended up going from the standard Luxury room at The Venetian (650 sq ft suite, 32-in flat screen TV and 17-in flat screen TV in the bathroom) to a Strip View Luxury room at The Palazzo (720 sq ft suite, 42-in flat screen TV in front of the bed, 32-in flat screen TV in the living room, and 20-in flat screen TV in the bathroom) for our entire stay. (Obviously, the longer the stay the more of a deal the $20 upgrade tip is worth.) (I spent some time on my last trip in a room in the Venezia Tower and it isn't as nice as The Palazzo. There's something luxurious about being able to control the curtains on the other side of the enormous suite with a remote control - something not offered in the Venezia Tower room I visited.)

What happens if there are no upgrades available (such as during a busy convention)? I don't have any experience in this, but from everything I've read, you get your $20 back. So if you're staying longer than one night and there are rooms worth upgrading to (for example, I wouldn't do this if I was staying at the Imperial Palace in a Deluxe room as the next level up is a "love" room with mirrors on the ceiling and probably very well used beds), it's certainly worth a try.
