A standard transfer is a point-to-point booking from one defined location to another, priced by distance. An hourly as-directed charter provides a dedicated chauffeur for a set time period on an open itinerary; the traveler directs the chauffeur to multiple destinations in sequence without separate bookings for each stop. Hourly as-directed service is best suited for executive assistants managing dynamic schedules, multi-stop meeting days, and programs where destinations are not known in advance.
