I have been to England four times, mostly Somerset and Dorset and just returned in March. In Dorchester, I stayed at Bramlies B&B which is reasonable and close (7 min) to the Dorset History Centre. Sue really takes good care of you. It is not so easy to find accommodations within walking distance of the Somerset Record Office. Use Google. Public Transportation is generally excellent, but may not be available for the countryside if you want to visit the small rural communities. Also use Google to access the National Rail Service and bus service within the larger villages. Please respond if you have specific questions.
