I am really picky on where I stay, so I never use priceline. I typically go on vacations to cities where I would not drive. I want to be really central, convenient to me, within walking distance to a specific place and in a hotel that has been recommended for good stays. I know that I can get nice hotels on priceline, but they are not always the best deal.
I have got some really good deals booking through the airline. It typically gives me even more miles than what I would get booking through the hotel. I want to be sure my hotel room is nice and not filled of surprices. I never would go for less than a 4* hotel if I was to book on priceline.
Now a while back, I had to book an unschedule trip and hotel. I did my way and my sister did priceline. I paid less on both hotel and air fare. And I had the direct flight....
