Booked flights – additional itinerary ideas.

We booked round trip flights to London. Most economical choice even when I compared open jaw, extra and return travel, etc. We’re doing London and Paris, 16 days including travel time. I want to do London, Paris, and Loire Valley.

March 28 – 29 fly to London

April 13th late afternoon non stop flight back to US from London. So want to travel back to London the 12th.

Thoughts how to break this up, or if maybe we could throw a 4th destination in there? Interested in history, wine, culture, etc.
