We have used Priceline many times,and always hit a good price, beautiful hotel and lucked out with the beds -- we are a family of 5. Since Priceline doesn't guarantee the type of bed, and also says bids are for 2 people in standard room. But, like I said we lucked out and always had big room, with plenty if beds. Until this past august when we took our yearly mini vacation. Our hotel was beautiful, our room big and lavish, but only had 1 king bed -- for 5 of us -- 2 adults and 3 teenage girls.
We tried to switch rooms, but all the rooms were taken. We made the best if it -- turning a big chaise lounge into a bed and havingnmore blaanketsband pillows brought up -- im just glad it was a little long werkend 2 hours from hone getaway and not a long, important vacation.
We also found out that some hotels cannot even legally have 5 in a room. I guess for fire code too. In those hotels, a family of 5 has to book 2 rooms.
So, as much I love Priceline, saved a ton money, stayed in some lovely hotels worth way more than what we paid, I am going to be very careful next time I book that way. I guess you can request bed type ect, but we were told it isn't a guarantee and really depends on what the hotel has available. The hotel does not HAVE to put in a room that you request. And once you put in your bid you agree to pricelines policy including rooms are for 2 people. They fill up all the rooms from normal paying people, and fill the Priceline, and other related type paying customers last, with whatever is still available. So, if you go when it's not busy, your probably gong to be ok. But, if you go during a busy time, you may end up not so lucky.
If your a family of 3 or more, be careful when bidding!
