The web site that Anne gives is the place I stayed. Air conditioning - I don't know. I was there the end of March so needed a jacket. The lobby/lounge area had a fire going. This is not a posh hotel, but it is very nice and great after a long day of touring. You might check with Denise. I think she also stayed there before her river cruise last year. Her views would be more up to date than mine. But if I was going back I would definitely stay there again. Rather apply that awful pound conversion rate to something other than an expensive hotel. Loved sitting in the lounge by the fireplace with a "toddy" after a long day of touring. Since you will be with a teenager, the toddy part is probably out, but still a nice area.
