Does anyone know anywhere in Bristol (or near) that I could stay with two teenagers and 4 golden retrievers next weekend?  Thanks!

Travel lodges are usually OK about dogs, though not sure about 4, but at this time of year they would be fine in the car overnight.

Try looking at this site.  Don't know if they will take four dogs, but they are dog friendly and plenty to choose from.

Thank you all very much for your help.  A friend has offered to stay at my house with the dogs now so we're sorted thanks.  Best wishes.
