We tried to do the impossible, visit 3 major tourists traps in one day, but we pulled it off. I believe the key was in the scheduling, getting to Stonehenge before the crowds in the morning, hitting Windsor Castle late (4ish) after the crowd, in between checking out Bath as much of as you can in 2 or 3 hrs. Now all of this was orchestrated beautifully by our tour guide and driver ***. He ably transported us from London to all these sites and back in a safe and efficient manor, conveying interesting, helpful, and humorous stories throughout the day. For someone who doesn't usually enjoy tours, this one provided just what I needed. Thx
