This tour is so worth doing if you're spending at least 2-3 days in London! For any Harry Potter fan, you will enjoy the opportunity to see the filming locations - you won't watch the movies the same way again when you realize that you had been in those same spots! Better yet, our guide (Hannah Weasley) was incredible and kept our group interested and engaged the whole time with trivia questions, fun facts, as well as a bit of history related to London itself. The tour lasted about 2.5 hours and Hannah provided a great restaurant recommendation out of it to round out our evening. For the price (about 12 pounds/person this was an extremely affordable way to see the city, engage in our inner-Harry-Potter fandom, and have a lot of fun doing it! Highly recommend.
