Excellent experience, change is always difficult, but in this case it played out well and worked in our favor as the service provided was incredible and the cleanliness of the facility impeccable.
Very organized from entry into the facility to pickup by the shuttle.
Also, you have enough trips that my last two times I didn't even have to call for a pickup. The shuttle was passing terminal as I exited.
"Premium" parking was indeed worth the money, except getting to the "exit" following the signs was frustrating at best -- maybe a simpler direct-line would help that.
In particular, the prompt service during the pickup process. Being quickly picked up takes the anxiety out of getting to the airport, since that's all most travelers are focused on at the time. Also, in general, the staff is courteous and helpful, from the ones at the gate, to the drivers.
