The dates we are visiting do not allow us to do the circle access so we are thinking of a group tour. We will not have a car and are thinking Windsor, Oxford and Stonehenge. Any suggestions? Sept 15 or 16. Plus where is a good location to stay? We are doing the typical tourist stuff like Buckingham Palace and maybe a Thames dinner cruise. Thank you.

Also are you asking on where to stay in London?
Are you only in London for 2 nights or are those September dates when you want to try to see Stonehenge.
The Premiere Inn at County Hall is adjacent to Jubilee Gardens, right next to the London Eye and across Westminster Bridge are the Houses of Parliament. Blocks away are the Churchill War Rooms. From the hotel Location to Buckingham Palace is a 25 minute stroll. 20 minutes to Trafalgar Square or the Horse Guards.
Were you looking for a tour that covers Windsor, Oxford and Stonehenge in one day? I'd say that is too much.
You ~can~ do this Stonehenge your own. Take the train out to Salisbury. At the Salisbury train station, pick up the local shuttle out to the stones which is run thru the local bus company, Salisbury Reds. Buy your ticket from the driver and get the combo one that gives you entry to Stonehenge. At the parking lot at the stones the driver will hop out, buy everyone's tickets and then you'll proceed to pick up your audio guide. You'll take the land train shuttle out to the stones. I like to walk back to the Visitor Center via the Cursus and burial barrows. You can catch the shuttle back to Salisbury and get off at Old Sarum if you like for a short visit. You'll probably have time to go see Salisbury Cathedral if you like.
Don't try to include Oxford, that city deserved at least a full day.
Windsor Castle is a must see, but not sure you can pull off Stonehenge on the same day. Do some trip planning.
Viator has a tour that runs almost 12 hours that does all three, but I wouldn't recommend that.
