We went wine tasting in Temecula, and stayed at Pechanga RV Resort. The staff is friendly, and the park is really clean. Wine Country is just 15 minutes away, and some wine tour companies will come to your site and pick you up. Our three night stay wasn't enough for us and we stayed a whole week. They have package rates available for extended stay. Overflow lot is available sometimes for dry camping, but the park is so beautiful I would recommend staying in the park itself!
