Avis are the only rental place in Whistler, one way drop offs will have an additional fee.
$400 for a private mini bus is pretty good.
Gas is $90 each way in one of those vehicles, its a 6 hour round trip for the driver and they have fees at the airport… so after fuel/wages, they take $100 but that's without paying for the other vehicle expenses, admin staff, reservation systems etc!
Basically they have to run a fare paying service each way to make it worth while.
Plus, they seat 10, so if you fill it thats £20 per person.. thats pretty cheap IMO. (Our van does 7 people plus driver with 7 bikes and luggage)
Alternatively, a scheduled bus – Pacific Coach at about $65 ($40) per person….
Cheapest transfer is to book a weeks holiday package with us.. transfer is free that way 😉
