I did a the same itinerary on 9/5 leaving on 9/8. (perfect Catherdral/Summit/Knife Edge day Friday). Just enough for the round trip. I did turn off the climate and the interior lights, and din't lose that much. I did hear a comment on one of the Tesla podcasts that a "camping" mode might be coming in V10. Wasn't sure if it was an entertainment thing or a real, shut it all down to save charge idea.
That threads suggests Keep Climate On and other tips for Model 3 camping:

Obviously, a dedicated mode makes things easier since there would be no settings to reset.
