Oxford/Blenheim

Your choices for the third day are all excellent. however this is too much to cram into one day. I would suggest hiring the car for two days. One day you can do Oxford and Blenheim (Woodstock the village right outside Blenheim has a very scenic main street with some very olde worlde coaching inns/hotels- definitely worth seeing. This will easily be a full day The next day you can go southish and do Salisbury, Stonehenge and Avebury. Another full day. I would consider doing Salisbury last and train from Salisbury to bath (easy ride) if you must do Bath. It may be possible to squeeze Blenheim in with Salisbury/Stonehenge/Avebury and drop oxford if your time is tight- but that wouldnt do justice to any of these

Thank you so much. I think 2 days sounds better. Any experience with renting a car from either Moreton-in-Marsh or Oxford one way to Salisbury?

If you don't mind, where are you staying in Stow on the wold? I'm considering a similar trip and would like to know your suggestions. Thanks! Suzanne

I usually rent closer to London- Reading or Guildford. However i would expect you will have more choice at any known name in Oxford (I recommend reserving an automatic).. you especially need to find a company big enough to allow you to drop off at a different location. moreton is a much smaller town with fewer choices i am sure others will have numerous recommendations

We are staying at the Cross Keys Cottage, because they had openings the nights we needed and emailed a response to my inquiry. We have difficulty calling so I prefer making first contacts by email or on their websites.
