I must also agree with the the response above from BRITSKI99, that ALAMO usually offers the best deals. I travel to MCO quite frequently and I use ALAMO 90% of the time. I also use Alamo in most other places I visit when available. Alamo also offers 10-15% discount if you pre-pay your reservation. I also have good luck with Thrifty Car Rental and Dollar Car Rental from time to time.
