That's a great price. I have been getting horrible rates and am tempted to go with Priceline. I have never used them so I'm not that comfortable with it. Have you used them before? Any tips I should know about renting through them? Thanks in advance

. Sometimes I will re-check the Hotwire rates to make sure they are the same. If they go up then I stick with my $1 a day increase. If they go down, I retry a previous failed bid.Priceline is *great* for rental cars. I wouldn't book too far in advance, though. You never know what will happen and your reservation is non-refundable.
The following companies work with Priceline:
Hertz
Avis
National
Alamo
Budget
Quick tutorial on how I bid on PL:
(1) Go to Hotwire and check your dates for a car and write it down for each car class you would be interested in. Be aware that the smaller cars are not always the cheapest! I would personally not ever bid on an Economy sized car for a family. Many people report being upgraded to a Compact for free but I have also seen people "stuck" with the smaller car. I usually create a quick spreadsheet with this information.
(2) Calculate 60% of the Hotwire price. This is your starting point. How does that compare to your current reservation? Remember to take into account taxes and fees, there will be more fees on a Hotwire or Priceline reservation. If your current reservation is less, then you cannot do better with Priceline.
(3) Have a maximum price in mind. I know that I would prefer to rent with National/Alamo in the airport at MCO over Avis/Hertz off the airport and a few dollars savings is not worth the extra hassle.
(4) Start bidding on Priceline using the number calculated in (2). You may rebid if you change the car type. I will bid a few types (typically Compact, Midsize, Standard, Full Size) in one sitting. If a bigger car is available for your bid, but a smaller is not I think that you will be upgraded so bidding the same amount for each car type is a waste of time.
(5) IGNORE any comments that Priceline makes about "good chances" and "great chances" when you enter your bid. They are designed to trick you into paying more than you have to.
(6) If your bids are rejected you may try again in 24-hours. I will increase my bid by $1 on each car type per day. This is where the spreadsheet comes in handy. Sometimes I will re-check the Hotwire rates to make sure they are the same. If they go up then I stick with my $1 a day increase. If they go down, I retry a previous failed bid.
