We are going on the British isles cruise in sept and am really into looking into tours now. We like to book through the cruise even though there more expensive we like the convenience. Anyways any tips. Nothing to strenuous since hubby has knee issues. Checking the tours in DCL website some say strenuous just how strenuous. Can he stay with the bus if it’s too much for him. So far we have the blanery castle anyone do any of these tours. Open to all suggestions and tips. Thanks
