Parked at Blue Sky for the first time a few weeks ago and couldn't have been any easier at half the cost of airport parking or taking a cab or uber from my apartment.
Check out Groupon for a deal and pay ahead to save some more money. I parked in uncovered parking and had no issues, there are cameras all over and a high fence. They pick you up at your car and take you to your terminal and it takes all of about 10 minutes. I was a little unclear where they pick you up upon arrival back to PHX so I gave them a call and they were there within 5 minutes, I probably should've asked when I first parked but no issues there. Keep your ticket that they give you when you first park and they'll drop you off right at your car. Tip the driver too. I parked for 3 days (I think) and it was around $32.
