It's easy to use the app, the location is conveniently close to the airport. I've never had to wait more than 15 minutes for a shuttle, and most of the time it's less than 5 minutes actually. As a bonus, they have water for you on your return.
It was easy to do, you scan a qr code when you arrive and they tell you where to park and a bus comes to pick you up from that spot. They also help you loaf your luggage. Then drop you off at the terminal.
Quick and effective. I had a shuttle there quickly after I parked. After a bad experience with economy parking through MCI, I will always go with the parking spot. They’re dependable, and they always run the right amount of shuttles.
