It actually worked out very well! Super simple process. Price and coverage was as advertised!
We arrived at their little building, which was super close to the ship, showed our drivers license and were given the keys. We got a little Kia Picante, which was practically brand new (only 1100 miles on it.) We zipped around the west coast with ease! The only hiccup was that when we got back to return it, the office was locked. It took us about 10 minutes to locate someone to drop the keys.(No key drop box, which would have been super helpful) Apparently a worker failed to show up to work. But we located someone in the parking lot and we were quickly back on the ship.
We would definitely use them again in the future! As a reminder for everyone, it was Smart Wheels!
