Using Blue Sky was a smooth and easy experience. We didn't realize that when we purchased our Groupon that we needed to put that info in on the website when reserving our parking spot, however, the cashier on the way out was extremely nice and gave us a punch card for a free day in the future to make up for the difference.
We left one of our cars here for six days while getting married in Florida. The shuttle picked us up right at our car when we dropped it, and the return shuttle dropped us right back at our car on the way out - really excellent service and FAST with the bags and drop.
They are close to the airport, so the shuttle ride is short and the drivers were professional. We will be using them again if / when we need to drop a car for a vacation!
