My wife has zero interest in flying except as a mode of transport. So if we're going somewhere we'll fly whenever we can and that works fine :-)
Though she won't touch the controls she's a good P2, reminding me of clearances and reporting points and cross checking waypoints if we're VFR as well as spotting traffic.
We've been all over the place and for her it means trips to places we wouldn't otherwise get to and/or trips to places we regularly go (e.g. Channel Islands) with less hassle and/or making day trips feasible when they otherwise wouldn't be.
