Looking into getting a rental car from Orlando International - however, I am concerned because we would need to rent the car around 1200 (flight lands at 10:48am) and then 7 days later we would drop the car off around 300 (flight leaves at 445). I don't want to drop the car off any sooner as we will have a toddler with us so the less time sitting around in the airport the better. However, every rental car I have looked into seems to be charging me the full daily rate for just those 3 hours over the 7 days. :
Rental car days are usually measured as 24-hour rental periods, with a 59-minute grace period.
Extra hours tend to be around 1/3 of the daily rate, so, after 3 full hours, you've paid for another day.
One idea is to have lunch at the airport before renting your car. In other words, start your rental later.
Another idea is to return your car early. You've said you don't want to do that, but, again, it might be worth planning lunch at the airport. Also, Orlando Airport has a large shopping concourse in which a toddler can run around, and there are some shops that are fun to visit.
Finally, consider springing for the extra hour or two if the hourly rate isn't too bad.
Be sure to look at the official rental start time when you get your paperwork. In the old days, they would stamp the exact time that you were handed the car keys. These days, paperwork is often prepared in advance based on your reservation time, especially if you're in the rental car company's "club" such as Hertz Gold. I've seen paperwork that's been off by more than an hour in either direction. That could be significant.
