They shouldn't Rates are determined by miles and time/length of trip. The only time they alter is if there is a Surge in place. In all our rides, and they total in to triple digits. I've seen surge less than 5 times. It happens but rarely lasts longWe are staying in a hotel near MCO for 1 night before a cruise on January 3. Thinking of heading over to MK resorts for dinner and to see the holiday decorations if they're still up. Do the car prices back to the airport differ significantly if later at night? Say 10 PM or so?
