We did a full day tour into the countryside to first visit Windsor and Windsor Castle, then on to Bath, and finally to Stonehenge. One very unusual aspect of this tour was that we had 50% Japanese guests on the bus that did not speak English so our guide had to repeat everything twice.   You will hear some of it on the video.

At Windsor we basically walked around the castle complex as there are limited rooms you can go into and our tour did not include them.  We had to wait the longest of almost anywhere we have been to to get in and we of course had a group ticket.  Interesting to see more of British Monarchy history.
