Tiger, we aren't moving to the dark side -- I absolutely had to have cell coverage -- my students were taking an exam, so I needed to be available. Plus most of the boondocking in the Sierra is out of reach in the winter -- the forest service locks the gates until the end of snow season. So Yosemite was almost our only choice. Plus, Upper Pines is so amazingly well-located -- it is right at the east end of the valley, right at the trailheads.
And the trick to making Yosemite look like a remote area is easy -- just hike above the valley floor, and the crowds thin out right away! Also, go in the off season -- I would imagine that in summer, even the more difficult trails can get pretty busy. I have not been there in summertime since 1959 -- to quote Yogi Berra, when asked about how he liked a very popular restaurant: "Nobody goes there anymore. It's too crowded."
