This location is at the airport, and where you go to clear packages with customs issues (customs is in the same parking lot)
Once customs issues are resolved, they're always fast and efficient.
It would be nice if you could park closer to the door for heavy packages, but it's not that far. It's possible loading by their door is allowed, but I'm not sure and didn't have anyone to watch my package or get the car.
Your milage may vary, but remember that they have nothing to do with holding your package for clearance, that's all customs.
