Tips

To extend the trip, add a day in London to visit the Science Museum and a day in Paris for Disneyland Paris (if you change your mind). To shorten it, combine the Windsor visit with Day 3 by taking a half‑day tour and skip the West End show, using the saved time for a quicker transfer to Paris.
