Fantastic experience. We had a grad time with Chris as our guide for the afternoon. We seriously would have been totally lost without his expertise & knowledge of London. He was awesome. Kind & helpful in so many ways. An experience we will treasure forever with Chris as our guide. Highly recommended for anyone who doesn't want the stress & hassle of trying to figure out the city let alone the modes of transportation. We were able to do the express train, tube & a double decker bus. Such a fabulous day. :o) Thank you Chris for making our day one of the best ever!!!!!
