Stonehenge-Bath -Windsor castle

Goldentours.com look under Day tours and premiumtours.co.uk

Would recommend going to Windsor first, it's larger than people expect.
I had also overheard a Windsor guard talking to a tourist who was trying to get into the castle quite late in the day, saying the only people who are allowed to do the late entries were the ones who bought tickets directly from them, from their own box office and web site. Since that tourist had bought their tickets from some other service's web site, they were not allowed to enter late. So that could be good to know as you plan your travels :)
Have fun!

If you have enough days, I'd do Windsor as a day trip from London. It’s very easy to do if you can find a tour of Stonehenge and Bath alone.

I’m not much of a fan of that combo either as you are driving quite a distance and not spending enough time (in my opinion) at either location.

I do understand having a short time frame and wanting to see a lot.

Bath can easily be done by train from London (Paddington). Pay on the day can be expensive - cheaper if pre-booked - with the cheaper Advance fares appearing about 11 weeks ahead - though even buying the day before can save money.

I did this trio once on daytrip by bus with the Evan Evans company. In fact, I've done four of their trips, including a daytrip to Paris. They run a good operation, check it out!

Premium Tours has an excellent, all day, tour of Shakespear's Home/ the Cotswolds/ Bath and Stonehenge. If you can, ask for Frank as he is an excellent tour guide and one I have used in the past. The tour starts at Victoria Coach Station and is quite enjoyable and informative. Stonehenge/Bath Tour

They also do a tour of both Windsor and Buckingham castles. I have not used them for these (I did not know about it until after the fact) but still recommend the company as well as seeing these sites.

We did a R/T bus tour from London to Stonehenge and Bath and it was all day. ( I can’t remember the name of the company but it left from Victoria station.) I think that might be a very long day if you tried to squeeze in the castle there as well. Personally I would try to do just the castle and Bath and skip Stonehenge. It was kind of underwhelming in my humble opinion; you’re pretty much like “Yep, there are some rocks.”

We needed a full day to see Bath well.

Windsor Castle takes a half a day, if you go early and you might be able to see Stonehenge on the same day. Not sure about a tour that includes both.

We did Stonehenge and Salisbury as well as Avebury in one day, using a rental car.

Thanks so much for the advice! It seems one week in London is not enough...but unlikely I'll ever return so I'm trying to see all I can. I will have to consult with my group to see what our priorities are!

I would devote a day for Windsor. It is quite large. Go to the Chapel first since it closes at 4pm whereas the rest of the Castle closes at 5pm. When I went to Stonehenge, I spent two nights in Bath and went on the Mad Max tour. Mad Max gets you to Stonehenge early, before the crowds. They also tour other areas in the Cotswolds. It's a full day tour. You have a new appreciation for Stonehenge and the surrounding areas.

I also used Evans Evans for a three stop tour. We went to Salisbury, Stonehenge and Bath. They did a very nice job and it was great to let someone else do the planning and driving. But three stops in a day is too much. You only get about 2 hours at each location, which is not half enough. I would also recommend you do Windsor separately and plan on a full day. It is absolutely wonderful. Then a day trip to Stonehenge (better than I thought it would be) and Bath. You can easily get to Windsor by train. Maybe find a tour that does just Stonehenge and Bath, with more time spent in Bath than just a few hours.

From what the tour guides tell me, they really recommend the two stop tours, but the public clamors for three stops. They think they are getting more for their money, but they are not.

DON'T RUSH!
