We are a group of 6 adults who will be travelling around BC next Dec/Jan. We are looking at a week or so in Banff, followed by Sun Peaks then Whistler. We're having trouble finding the best way to transfer between Sun Peaks and Whistler. Our planned transfer day to Whistler doesn't line up with the direct coach. We've looked at flights and the train to Vancouver then a transfer to Whistler, but thought a private transfer might be a more cost-effective and direct option. However we can't find any shuttle companies mentioned on TripAdvisor forums. Any suggestions?
