Hotwire tells me that they have a 4* available for $90/night during my stay and yet they are also offering 3*s for $120. Should I be suspicious? I've never used Hotwire before so I'm not entirely confident with it yet. One more thing...is either Hotwire or Priceline favorable (one over the other) in terms of the quality of hotel they offer? Thanks!
EDIT: One more thing...those of you with experience with Hotwire, do you recommend booking a month in advance? Or is it generally worthwhile to "wait to the last minute" in the hope that something great will pop up?
