The agent was very helpful and was able to get us a car DESPITE the fact that our reservation was for pickup in downtown Orlando, NOT at the Orlando airport. She saved the day for us.
The line for pickup was 2 hour wait. Very crowded. Kayak/Priceline had the reservation as pickup in downtown Orlando, NOT the airport, which was not clear. I had indicated pickup at MCO (airport) Be sure you understand where the pickup is as this can totally mess up your day. Luckily the Dollar agent was able to get us a car. The agent said she sees this switcharoo for pickup location frequently with reservations through Priceline. MAKE SURE YOU KNOW WHERE YOUR PICKUP IS!!!!
