I will be taking a trip to London this summer with my hubby and 3 kids it will be a sixteen day trip. I have never been to Europe and would like to see as much as possible without being too rushed. I will go to London and see the traditional attractions for sure ,and would like to see Bath, the Cotswolds, and the kids want to see the Harry Potter attraction. What other countries could I fit in realistically via Eurostar train (?) within my time frame. Open to itineraries...France, Scotland, Belgium???? Thanks for any help!!!!
