Thank you all! :-)

Flights are unfortunately now fixed Vancouver to Vancouver - made using airmiles and challenge to get anything and hence why it is booked a year in advance.
Had option of adding an internal flight, but for the family, luggage and the extra one-way charge for hire car, was around $1000 Canadian more than a pick up and drop off at same place and doing the extra 800km return.

So that leads to the attached.
Thoughts?

We all, including son absolutely loves all things outdoors, so really excited for it.
