This place does weddings and also has accommodation. Also it is close to Stirling, Glasgow & Edinburgh if you are sightseeing - http://www.culcreuch.com/ - and I have to admit a preference as it is also the ancient seat of the Galbraiths.
If you want something really historic this place does weddings and has limited accommodation - and also brews its own beer. It is not far from Peebles in the Scottish borders - http://www.traquair.co.uk/

Hope all goes well and as others have said you really do need to hire a car to see the country properly.
