We will be in Sedona for a few days and then flying back to Canada at 8:30 pm on Tuesday. What do you think is a good time to leave Sedona that day? The gentleman at the car rental place said to allow well over an hour to return the car and get a shuttle to the airport and suggested arriving by 5:00pm. He also said that since it will be rush hour in Phoenix, that the drive from Sedona would be a good 4 hours. I’m all for allowing ample time but I’m just checking to see if this sounds reasonable? Since it’s our first visit, I’d really appreciate any advice.
