Well, since it's my scenario, I can assume whatever facts I please!
Now, moving away from my scenarios, I know that if I'm on vacation somewhere, I'll try to get training with a local CFI and would like to have my spouse with me in the plane. It truly has multiple purposes. I always want additional training. I like having a pilot familiar with the local reporting points and area. And I like doing some sightseeing. Personally, I think that's clearly a training flight and not an attempt to skirt the part 135 of flightseeing rules. I think that it passes the duck test.
