It depends on what you want. I live in Virginia. You could spend time visiting DC, Arlington and then head to Shenandoah for a mountain cabin retreat! I'd recommend this April though October. Or come to visit me at the beach!
Or you could go to Florida for the emerald coast, white sand and warm weather.
You could go to Vermont, for skiing, cheese and mountain trails.
November is still a great time to come to LA. The weather is still really nice (we’ve spent many Thanskgivings in shorts, shirts and flip-flops haha). It can get a little chillier in the evenings, but a sweater and some long jeans should do just fine. If you go to Santa Monica, it will be much less crowded and more quiet in November, which will make it a little more relaxing and romantic (in my opinion).
Wine Country (Sonoma & Napa) are world famous for their amazing wines, but that’s literally all there is to do up there, is drink wine. Plus that will be over a 7 hour drive from LA. If you want some wine that is arguably as great as wine found up north, then I would suggest spending a few days in San Luis Obispo (it’s where I’ve been living the past 2 years and is about a 3 hour drive north of LA, so much closer than Napa & Sonoma). The wine scene in Paso Robles & Edna is huge (my favorite is Wolff Vineyards in Edna; which is a 5 min drive from San Luis Obispo). Plus, coming to this area, you’ll not only have plenty of fantastic wine to try, but there are other things to do that would make a few days here memorable and worth while. If you decide to add this to your trip, I have tons of suggestions for things to do and see, and restaurants with terrific food.
