Last fall, I rented from Dollar for the first day of an 8 day trip. It allowed me to eliminate the cab fare and make a grocery run for the week. When I returned the car to the Rental Car Center, Dollar gave me a free ride back to the hotel. This trip, I've booked through Enterprise. I will take the free shuttle from the airport to the Rental Car center and then return the car the next day. I was wondering if anyone else has experience with shuttles from Enterprise or other companies. The Dollar driver said that they will pick you up at your hotel if you needed to rent a car. Seems like an unknown perk.
