Our trip is not until October, but I am a planner. I have a rental car booked for our trip, and it is the first time renting a car. Our flight arrives at 8am on Saturday, and I am setup to pick up the rental at 9am. Is that a large enough window? Or should I change the pick up time? And on drop off, our flight leaves at 7:15am on Wednesday, setup to drop the rental off at 5:00am. Will that give me enough time to get to the airport and through the process to catch my flight?
