I've used both over the years but it's been a while, now I have identical MCO ressies in Oct - Nov only $4 difference and I'll be cancelling one at some point. Anyone have a notion as to which I should keep as I can't recall any problems with either, or any rental company we've used for that matter. Also, I belong to both Dollar Express and Alamo Insider.
Bill, we have used both multiple times and never had any problems. Not sure about Alamo, but I do like that Dollar offers a nice pad if your flight is delayed. I think they still hold your reservation for several hours.
