Honeymoon – France and??

We’re planning 15-16 days including travel time. Paris and the Loire Valley are top of the list. We do want to pair another country but are torn about what will be best. It’s either England, Spain, or Italy. We first thought Italy, but now I’m leaning toward England or Spain.

Any thoughts? We don’t want to try to do too much, but we’re thinking we could do a full week in each country and limit travel within to 1-2 places?

We’d be going end of March/early April (leaving before Easter) 2024.
