Hi I have had mixed results pre booking a ride with uber. Our drivers have told us, Uber just sends out the ride request when it is time to get your ride to you, so technically it isn't booked until that day when a driver picks it up. We just got off the Escape at Port Canaveral Saturday and used a private shuttle with cocoabeach shuttles. We exited the terminal and turned left. Our driver was waiting and we were off. If I sail from there again, I'd use them. It was really seamless and we had our driver's name and telephone number if we needed to reach him. I believe our ship was delayed clearing customs but from the time we exited the ship to the airport was about an hour.
