Europe, honeymoon destination, recommendations that are pleasant in February

Hi everyone! I’m getting married in January and we’re planning our honeymoon in Europe (France/Italy/Spain/Switzerland area). The only thing is, I don’t do well in extreme cold, so I’d prefer to avoid destinations where it’s freezing or in minus degrees.

We’ll be traveling from Delhi, and ideally I’d like places where the temperature is mild—around 5–15°C is fine, but not extreme cold that requires heavy winter gear. We’re planning for about 8–12 days.

I had Switzerland and Paris in mind, but considering the weather, I’m now thinking about Italy (Amalfi Coast, Venice, Florence, Milan, etc.) or Spain. Could you recommend the best honeymoon destinations in this region for February that balance romance, good weather, and not-too-heavy packing? Thanks!
