Got it, even without a Valet component I think you guys are onto something great but in the meantime I suggest changing the description and call this part of the service "free limousine ride" or even something more glamorous like a "Chauffeur service". A valet is someone who parks my car not someone who gives me ride. The best way to manage customer expectations is to under promise and over deliver. When you launch your valet service you can email all your customers to tell them they were upgraded to Valet service for free, you'll delight them instead of deceiving them.
