I had a flight change and now will be returning from MCO later in the day - therefore I'll probably return my rental car about 2 hours later than originally scheduled. I really don't want to hang around the airport for 4 hours. I'd rather pay a few extra dollars and stay at OKW. Doing this will bring my rental up to 23 hours on the day of return rather than 21 hours. It looks like Avis might not start hourly charges until you get into a new 24 hour period but I am not 100% sure on this. I was wondering if anyone had any experience with charges when they returned a rental car later than the posted time of return on the reservation. Do they generally start penalizing you by the minute if you are over the agreed return time? Is it wise to schedule the return of your car as late as possible as long as you don't cause yourself an extra day's charge?? Thanks.
