$20 Trick - It works very well
Just got back from Sin City. Arrived at Sahara around midnight. Checked what room was assigned to me. (12th floor, not bad)..........
Put a twenty on the counter and politely asked "are there any upgrades available". Clerk checked the computer........ Bingo. Given a 2-room suite overlooking the strip with (best of all) a walkout BALCONY.
All for the grand total of $43.00/per night.
I am one happy camper, second trip the trick worked. I suggest you give it a try. VEGAS RUNS ON TIPS!
