If you are coming from London I would recommend that you take the train from Paddington to Kemble. If you book in advance via the website www.thetrainline.com you will get a good discount.
Examples of suitable train times:
|London Paddington||Kemble||Kemble||London Paddington|
|Monday – Friday||08.30||09.50||17.19||18.39|
Alternatively I can pick you up from your hotel of course. If this is outside the Cotswolds area then a charge will apply.
