Oct ‘23 honeymoon ideas?

Hi everyone! Does anyone have any recommendations on an itinerary for a Europe honeymoon? We love the idea of going to Europe and would prefer to see as many things as possible in the 10-12 days we’ll have but since we have no experience with traveling over seas it’s stressful to try to plan. We were thinking Italy or Greece but open to anywhere. We also can’t drop a crazy amount on this trip either though our flights will be covered through card points. Also trying to factor in weather, we will probably be leaving the 30th of Oct and staying till first week of Nov atleast.

TIA!
