David - You can buy a pass that covers the 3 major museums - go to either
the Thyssen or the Renia Sofia first and buy the pass there - then you can
avoid waiting in a long line at the Prado. All 3 museums are within easy
walking distance of the Villa Real, which is a great hotel. The rooms are
especially comfortable and have a separate sitting area down a few steps from
the main bedroom part of the room. Ask for a room overlooking the Plaza de
Cortes. A taxi from the airport is reasonable - it's not a very long drive -
maybe 20 minutes in light traffic.
