Can you chance provide the link, I did a search (like a good boy) but couldn't find it.
My brother and his wife are only here for a week and I was debating whether recomending they take a tour or go on thier own. The only problem with Segovia is getting from the train to the old city, took us about 30 mins, thankfully the car rental office had a map to the TI, we had to stop several times to ask for directions. Once your in the old city its easy to get around and coming home I suggusted bus rather than train.
I found the following link for walking tours around Madrid
www.esmadrid.com walking tours are very very cheap under 5 euros.
Is the Madrid Card a good deal? Mark wants to see the following prado The palace and The thyssen art gallery and the centro de art reina Sofia (Picasso's Guernica) A 2 day pass ios 48 euros.
to answer your question, yes it is and that's good to know. Thanks
