Location was convenient - next to water taxi, near several hotels. Car was available to us 2 hours earlier than requested. Upgrade was offered, which we decided to take. Walk around the car and transaction was handled in short amount of time, there was no hard sell for additional cost items (the upgrade was offered, but not pushed), and we were on the road.
Finding the location was a bit of a challenge, but Hilton Hotel staff was quick to send us in the right direction and the challenge was well worth the convenience.
