Longtime Alamo renter here. However, pricing was so much lower to book Budget that we used them for a 3-night pre-cruise and 7-night post-cruise rental last month.
We picked up at MCO and dropped off at Port Canaveral for the first rental and did the reverse for the second. Pick-ups were a hassle both times. At MCO, I had to go to the counter because it was my first Fastbreak rental so they wanted to verify my license and credit card information. Long wait in line to talk to the agent. Then a long sales pitch for their various loss waiver (insurance) options, with quite a hard sell even though I have good coverage through my personal auto policy, an additional personal liability policy, and additional car rental coverage through an annual travel policy. Drop off at the Budget location near Port Canaveral was another long line. At least the shuttle to the port worked well. When we completed our cruise, we took the shuttle back to the Budget office near the port. Another long wait in line (no Fastbreak service there), followed by the agent attempting to raise the rental rate by $120 for the week-long rental, despite my reservation paperwork and the fact that the shuttle driver had told us they had over 100 cars on site. After getting that resolved, another attempt to upsell the insurance products before we were finally given the needed paperwork and told where to locate the car. Drop off at MCO went smoothly, although I did not like the fact that they would only email me a receipt. Alamo at MCO has always printed one on the spot using a handheld unit. I particularly wanted to verify the charges since the agent had attempted to charges us the extra $120 for this rental. Budget had pre-authorized an extra $200 on my credit card for the each of the rentals compared to the rental contract, but the actual charges for both rentals were correct to the penny.
I will continue to book Alamo unless the Budget prices are so much more favorable as to offset the additional complications. This last trip, the two one-way rentals would have been twice the price to use Alamo instead.
