Subject: Re: Economical hotel/b&b in Windsor, England area
If I were facing this question I would go to http://www.theaa.co.uk/hotels and refer to B&B's in Central England. There are several very nice-looking places with DDDDD (the best) ratings that doubles list for circa $100. There is one in Henley on Thames (Lenwade) that is worthy of a further look as well as some in Oxford.
