I have used the Parking Spot at a few different airports, and will admit that my initial decision was based entirely on the cute yellow & black polka-dotted buses. That was quite a few trips ago, and those dotty buses still have me hooked.
The Parking Spot in Phoenix is the best I have experienced. Very convenient and I have always been able to find a coupon either online or in one of those mail packets that discount the already reasonable $10/day for covered parking.
ARRIVAL:
After taking a ticket at the kiosk, signs indicate the row of spaces to use on that particular day. Each time a shuttle bus has pulled up right behind me as I am parking, and I am given a card with my space number so it will be easy to locate my vehicle upon returning. While this may not be unusual, I am used to the large parking lots at LAX where you park waaaayyy out in BFE and then hoof it to a central pickup point. So, I feel like I am getting super special service (even if I am not - don't tell me!)
DEPARTURE:
The easy to see dotty buses circle the airport frequently so I have never needed to wait very long for a ride back to the lot. Armed with the space number card I received on arrival, the driver deposits me right at my car (again, I am not used to this!). Check-out is very fast and the complimentary cool water is always greatly appreciated.
Save me a spot on the dotty bus - I will be back!
