My daughter and I had a great tour with Colin. His depth of knowledge about history, the university system, and Oxford is impressive. We spent our whole day with Colin, and every minute was informative. We saw many colleges and their chapels, each with a special story and character. We also visited the Ashmolean museum where you should spend more time than we had, so Colin showed us the most important highlights. At the end of our day, Colin even helped us decide how to prioritize our remaining time in London. We highly recommend this tour. We are from the Chicago area.
