I think London’s a good place to start due to the language thing. If your 10 days counts your flight to/from US, I’d stick to England/Scotland/Wales — maybe even just London and day trips. Day 1 is your flight over, day 2 is arrive and adjust day, and day 10 is your flight home, Day 9 is often "get back to starting point for flight home" day. If you have more time, try London and Paris — taking Eurostar between if you can afford it.

Remember that Northern Europe is farther north than most of the US. That doesn’t make it colder, but it does make the days shorter. It’s often rainy which can make it pretty dreary in November — not to discourage you — you’ll have a great time, just don’t expect sunshine.

I would go to Spain myself….I just really love it. I can’t think of anything special going on diurring that time but I did go there a couple thanksgivings ago and the weather was very pleasant.

thank you both.
