I just came back from renting a car in july. I had been pricing them for a long time before the trip. the rates have more than doubled. People have posted because the car companies have gotten rid of most of their fleet so they can now raise the rates, supply and demand. What I would highly recommend is book right now with the lowest rate you can find. Don't forget to use the codes from mousesavers.com. Then every now and then recheck and see if you can find something cheaper. You can always cancel the first reservation. I also tried priceline.com and found they were no better. Some people have also posted that you can rent from the car care center at disney and you can get a cheaper rate because you are not renting from airport. You would have to take the disney transport to your hotel (if you are staying onsite) and then you call the car care center and they will come and pick you up and bring you to your car. It explains it better on mousesavers.com.
