Going to Vegas next month (\\) and I recently discovered this trick. I had never heard of this until 10am this morning while looking for ways to get better rooms/views at the front desk.
If you are unaware of what this is, basically when you check in at a hotel you put $20 between your I.D. and your credit card and then ask your front desk rep if there are any upgrades/better rooms available. Apparently, this works a lot??

Reading some reviews--mostly seems to work in Vegas--it seems like it works pretty often (and recent too)
Has anyone had any experience with this? By no means is this illegal or anything? I can't imagine it would..
