I haven't posted to this board very often (since joining in late 2009) but I have to give my three cents worth of ideology regarding this subject. Money is nice, but it dosen't get what you want ALL the time. Sometimes a nice smile, or an unexpected compliment to a hotel clerk will get you (some of) what you would like----with no currency involved. I'm sure many clerks have been schmoozed for free upgrades or other attempts for freebies, and they see right through the soap bubbles guests have blown at them. They're not dumb, nor do they have the power to upgrade you from a "bottom level" room to a suite without explaining to management how that could or would have been appropriate. You get what you pay for, or what you have coming in comps. If you do get a "small" upgrade at no cost to you, feel very lucky and appreciative of that. It won't happen all the time. Upgrading to a strip-view room at no cost is probable but not guaranteed. Upgrading to a room that would cost an extra 300 bucks for a 5-night stay (at no cost) is not likely, so don't expect it or feel slighted if your "$20 trick" gets you nothing. There's my three cents.
