Whatever tour companies you are considering, look for reviews on "Travel Advisor" and maybe some other sites. We wanted to do some day trips from Madrid, and did not find anything that attractive either because of price or because the trip itself was so packaged, or the reviews just didn't excite us. Eventually we decided to take a chance and just do it ourselves. We used the train system, and just tried to stumble on interesting places to eat. And of course we had a guide book to direct us to the sites. Logistically it was much simpler than we expected, and I think we had quite an interesting time. The Spanish people we encountered were very happy to give us directions and advice of all kinds. Sorry I don't have the answer you would really like. Linda
