Back in February, we decided to rent a car through Priceline. Priceline allows you to reserve your rental car, but does not charge your card until you get there. When we arrived at MCO, we reported right to the rental company's pick up lane to take their shuttle. We waited 90 minutes and no shuttle. I found their phone number, called them and they said "Oh sorry we ran out of cars". So "reserving" a car on Priceline actually does not mean reserving a car. We quickly "reserved" another car for a company who's shuttle we actually saw. We just got on a crowded shuttle and were the last in line at the office. Every single person in front of us got up in arms saying things like "That's not what the website said!" "Where on Priceline does it say that?!" And sure enough when it was our turn, the price that they wanted to charge us was now triple what Priceline quoted. Everybody else gave in and paid which is what they're relying on, but I just called a Lyft. When all was said and done, I determined taking a Lyft was actually cheaper when you factor in parking at the parks/resorts. Be wary of using Priceline for rentals!
