My sister in law used EZ rental on our trip last march. We leave for this years trip on Tuesday, and she has another reservation for this trip. I use Alamo, so I can only say what she has told me. EZ is good beacause you don't have to have a credit card to rent a car. I know that she had decent rates for both trips. the only downside that i see is that she had to put down something like a $500 cash deposit, which she gets back upon return of the car. Also, If I remember correctly, she had to purchase the supplemental insurance because she had no credit card, which, in turn turned her decent rental rate, into a slightly higher rate. But for someone under 25, and with no credit card, what choice do you have? there is a shuttleservice from the airport (we used MCO), and I recall her having to stand in a rather long line at the actual office. She rented a minivan, which was in good shape. The tank was on empty when she got the car, and I believe it was not very clean. She was told to return the vehicle on empty.
Hope this helps, or is not too late.
