Cheap accomodation in 29 Palms or Joshua Tree (the village) (all have pools). Fly to LA or Vegas, whichever is cheaper, although Vegas is easier driving. Try http://www.highdesertmotel.com/
There is also sport climbing in Joshua Tree National Park, but NJC has more variety. Although JT has a pair of 5.2 sport, great for kids to try leading!
I used to be there every november, so have climbed a lot at that time of year. Lost 1 day in 2023 due to 6" of snow, but otherwise teeshirts and shorts.
