my wife does it, but it is different sites...i know expedia was one.....groupon...living social....a deal may pop up and then a day later not be there...coral seas did that a few times...missed out while thinking about it, then when it came back, i locked it in....you have to put in your dates and shop around...

i have not yet paid asking price for a room....always well below that...but we always go in low season...plenty of places with lots of vacancy...had this discussion with management at the above mentioned spots as they all want my returning business..i now have numbers to skip the normal reservation desk...
