We (Dominion Rail Voyages plus Morristown & Erie Railway) gave the client a quote of $33,000 for using 2 six bedroom lounge cars (MOUNT VERNON and ALDER FALLS), coupled lounge end to lounge end, for the MIA - NYP - TWO trip. That included deadheading from NYP to MIA before the trip and deadheading from TWO to NYP after the trip.
The client decided to pay several thousand dollars more to use 2 cars (coach/lounge MOHAVE and full sleeper PACIFIC UNION) from the midwest. I think the deadheading mileage expense was greater for these 2 cars. However, it gave the client the car types that they really wanted - a full sleeper plus another car that was all dining/lounge space. The aesthetic side benefit was they got two Budd built cars, one x-UP and one x-ATSF, whose exterior appearance (fluting pattern, trucks, etc) matched almost perfectly.
========================
Pricing a private car charter is not all that complicated.
First, add all of the direct costs associated with the trip:
TRANSPORTATION (all carriers)
switching
mileage
parking
sewage dumping (if applicable)
extra engine charge (if applicable)
CREW
chef
attendant(s)
crew transportation between home and trip point of origin/termination
FOOD & BEVERAGE
cost of all food, beverages and associated supplies.
CLEANUP
cost of cleaning car before the trip (OR) cost of cleaning car after the trip.
laundry (bed linens, table linens, towels, washcloths, etc.)
MISCELLANEOUS
diesel generator fuel consumed
fresh flowers
other extras
any special requests by client
After you have added all of the above to compute a total cost, you then add a daily lease fee to obtain the client's total cost of the charter. The daily lease fee covers the car owner's General & Administrative expenses and his (return on investment) profit. The daily lease fee can vary day by day. For example, we use a different lease fee for:
client occupied day, moving
client occupied day, parked
deadhead day, moving
deadhead day, parked
