Thinking of South Korea for honeymoon in mid-November – Need advice

Hey everyone, My partner and I are planning our honeymoon and we’re seriously considering South Korea for 7–10 days around mid-November. I’d love some genuine advice from anyone who has been there or looked into it.

We’re choosing Korea over Bali and Thailand (which are also on the list) mainly because it seems like there’s a lot more to explore – culture, city life, scenic beauty, K-drama vibes, etc. But I’m not sure if November is the best time to go or if there’s something we’re overlooking.

Some things I’m curious about:

Is mid-November a good time weather-wise?

Which places/cities should we focus on in a 7–10 day trip?

Any must-do or must-avoid experiences?

Is the language barrier a big issue for tourists?

Would you recommend Korea over Bali/Thailand for a honeymoon?

Would really appreciate any tips, recommendations, or things to watch out for. Thanks in advance!
