We just used this service for the first time in about 10 years, and it appears that the owners have changed since the last time we used them.
The employees were great - very friendly. And the shuttle service was very fast - which is exactly what you want to see, after you come home from a really long flight.
Something I didn't like was that they insist that everybody really pack their cars in pretty close to each other, so it felt a bit scary driving around the lot to get to the self-park spot, it felt a bit uncomfortably close to have the car so near the neighboring cars.
And then when we came back, there were cars double-parked behind ours that needed to be moved before we could go home.
I still think this place is better than the Park N Fly value lot - just because the Park N Fly value lot has poor shuttle service, even though their actual parking spaces were nice and wide. Also with this place, there's an attendant who helps with payment up front, so then you can just go home when you come back.
In sum, I have mixed feelings about this place - we may still use it again, because it's got a great price. It wasn't without it's drawbacks though.
