Hi folks! I am coming to London for 4 days (on our way to a Switzerland train vacation) with my older mom. She can get around, but slowly, so we can't rush around hitting all the sights. We have both been to London before, and are most interested in museums, plays/musicals, good food and general sightseeing. We don't need to squeeze every last tourist attraction in, but would rather move slowly and see a few great things. We are staying in South Kensington near Victoria and Albert Museum, and our trip is May 7-12. Any advice is much appreciated!
