We chose the Long Beach office to drop off our rental car. I was told the office (it is just a room) closed at noon on Saturday. We hit some bad construction traffice so we did not get there until 11:40 AM. No problem, they never opened that day!
There was an 800 number on the door and they told me to drop off the car at a hotel around the corner. I did and we took a taxi from there. The taxi was just over $20 and the ride took around 15 minutes.
BTW, I could not believe the car rental rates. I think our car was $42 for two days. It was cheaper to rent the car than take SupperShuttle once.
We did take SupperShuttle back to Orange County (John Wayne) airport. That was $60 for three people. In addition, our reserveration was for 9:30 and we were off the ship by 8:00 and had our luggage. I was not looking forware to standing there for 90 minutes and as soon as we stepped outside, there was SuperShuttle stop. The van parked there was going to our airport so we took it. I would definitly take it again.
