Hi there!
Although I have not used this rental car company, I wanted to throw in my two cents about rentals in general!!
In my intense research for our upcoming trip I found the best deals to be throught the car rental agency websites themselves. Also, the farther out you book your vehicles the better rate you will get. Of the times that we have gone with a rental Alamo always seems to be the best deal. I used the Entertainment book rate (along with a coupon) and got a rate of 483.00 for a van for 15 days. I booked this in June. If I were to go onto their site now and use the same coupons I'd be paying more than double!!
So regardless of which company you go with, book early!
Sorry that doesn't really answer your direct question, but hopefully it will help you decide which company to go with!
