How does valet parking work at BOS Central Parking?
 

As many BOS flyers likely know, for a while now BOS has used valet parking at Central Parking during periods of high demand. The airport parks the cars in various spaces throughout the airport, including squeezing them in every nook and cranny at the airport.

I have never had this happen to me, but I am curious as to how it works out. Do they ask you when you return so they know when to have the car back at the garage? What if your plans change and you return early? Some cars are parked 10 deep, so handling all of the movements must be a logistical challenge.

I look forward to hearing your insights and experiences.
