The spots you actually hit on this tour are great, but I think the order of the trip--Windsor, Bath, then Stonehenge--is a little backwards. Stonehenge seemed to me to be the least impressive part of the trip. It really takes about 10 minutes to learn about and explore the whole formation, yet it was the last thing we did--a little anticlimactic. Every place was beautiful, but absolutely rushed, and our tour guide was informative and slightly hard to understand. Definitely nice to get in to all these places without lines or hassle, but if you really want to see more of Bath, I would recommend making it a whole day trip in itself.
