We've always gotten a car at the airport in the past, but using ME this Aug and will rent/return on property. Is one of these two places better than the other? We rented from Dollar last year and they tried to charge us for a pre-existing scratch the size of a quarter , so we want to go with the most reputable and customer-service friendly place. Would we just take the boat to the Dolphin to pick up? Is it usually very busy there & can you choose your car like they do in the airport? I'm leaning towards Alamo but maybe Avis at the Hilton is better? Both are midsize for same price; Avis would be a Chevy Cruze while Alamo would be a Hyndai Elantra.
