Prepay for everything and opt for purchasing the full tank that way when you get to the airport you are directed to a lane to park, leave the keys in the car and head on your way.
Returning the car is much quicker. You basically are greeted by someone and then if you haven't prepaid there is a booth down by the cars. You don't need to go back up to the counter. I'd guess about 15 minutes. They have 2-3 Lanes. Just watch carefully for the signs as you get to the airport... It's well marked. Also double check your bill. They had charged me $169 to fill up the tank despite telling them when i rented it, I would fill up the tank which I had when i returned it. They did immediately adjust my bill... but geez!
I don't know. Always try to rent and return during the week....cheaper!
