As balzaccom mentions, that late in November is going to get sketchy in terms of weather. You're going to be very much dependent on forecasts, and you're going to be coming up against issues like trailhead accessibility and even some closures of both roads and trails themselves. If there is snow on the ground already, as well as any in the forecast during your trip, it's time to either reevaluate your gear, your skill sets, or even the trip itself. It's not just a matter of enjoyment, logistics, and safety, even not far out into the wilderness, it can be a matter of actual survival in the wrong circumstances.
That said, you're pretty much relegated to trailheads based in the Valley. By far, the best choice for multi-day, low altitude is the North Rim. For this, your trailheads will either be Yosemite Falls or Snow Creek, both fierce climbs. In either case, once up, all camping is dispersed, preferably in an existing site, with the only restrictions being that you must be at least 1/4 mile beyond the brink of the falls, and that you may not camp south of the footbridge on Snow Creek.
Aside from that, dependent on conditions, the trailhead at Happy Isles (the JMT), up to little Yosemite Valley, then beyond, either up the Merced River or towards Sunrise Creek is another good bet. The South Rim via the Four-Mile Trail is already likely to be closed for the season by the time you get there.
