Thinking of going as a day trip from Oxford. I have had a look at the train an bus time tables and this is what I have planned:
9.21 train from Oxford to Moreton-in Marsh Arrive 9.58
10.43 Bus #22 to Chipping Campden Arrive 11.12
12.45 Bus #21 to Moreton-in-Marsh Arrive 13.27
14.10 Bus to Bourton on the Water Arrive 14.37
17.35 Bus to Moreton-in-Marsh Arrive 18.00
18.07 Train back to Oxford
What do you think. Will it be too much for a day?
