We had originally booked a full day starting with Windsor Castle Lunch at Harrods and afternoon Tower of London. However the afternoon portion was cancelled and a voucher issued during the trip. The pick up point was very convenient and the guide pleasant and friendly.The Windsor tour was wonderful we even had time to see the changing of the guards. We had enough time to do some shopping in the town. We stopped into "Woods Of Windsor" which has been selling perfumes etc to the Royal Family for over 200 years. You can only buy these items at that location. Lunch at Harrods was really a nice experience. Elegant and unhurried, just what we would have expected.
