It seems like there might be some confusion with the location and transfer details, as Dandenong Ranges is in Victoria, Australia, while Calgary is in Canada. If you meant to stay in the Dandenong Ranges, Australia, I'd be happy to help create a retreat itinerary based on that.
However, if you’re referring to another location or need a different private transfer setup, please clarify, and I’ll be happy to adjust! Below, I'll proceed with an itinerary based on Dandenong Ranges in Australia and Calgary as the starting point for travel.
