I highly recommend the private guided tour. We avoided standing in long queues and were quickly navigated through the grounds. Ana was incredibly helpful even before the tour began by recommending tips for a quicker route to arrive at Windsor from downtown London. She was able to tell us what may be more interesting for me and my children (ages 8 and 10). She was very informative and helped my kids adapt to their surroundings when they had questions as well. She made the tour highly enjoyable!
