I usually try to use Alamo, but last trip used Budget because the rates were so much better that time. Budget worked out fine for me and, although Alamo is still my choice, I would use Budget again. Same is true for Dollar.
A few observations:
- Alamo is probably the easiest as you can do your checkin online, skip the counter entirely and go right out to your car. Joining Alamo Insiders isn't a bad idea, but there are often better discounts with other organizations. If you don't completely do online checkin, but have a reservation, you can also use one of the Alamo kiosks, which are next to the rental counter in the airline terminal. There's rarely anyone waiting at the kiosks and it only takes a couple minutes.
- If you use Budget, I would also encourage you to join Fast Break and tie that to your reservation. That way you can bypass the counter in the terminal and go to a much quieter FastBreak counter in the garage.
- On the additional driver issue: that seems to be more related to the affinity program you have with your reservation. With no codes, I don't believe any of the agencies give you a free additional driver. I'm not aware that the additional driver comes automatically with Budget. But, for example, if you are a Costco member and use a Costco code with Alamo, the additional driver is included. I imagine there are similar situations with other organizations.
- One other thing with Budget to be aware of. They have a SunPass transponder attached to the windshield. If all you're doing is driving to WDW on the toll road one time, then back when returning to MCO, it isn't worth using. You have to be very sure you completely turn it off...there's a big switch on it. Better yet, remove it from the windshield, turn it off, put it in the console or glove compartment, but remember to put it back before returning. It is held on to the windshield with velcro tape...if you have an EZPass in the northeast, you know exactly what I mean.
