What a wonderful trip. This is a new trip to CGT but was well organized and full of activities and discoveries. We had 4 days each in Madrid, Valencia, and Barcelona. As in all European trips there is a lot of difficulty terrain and lots of stairs. Some of our travelers stayed on the bus or got to an area and went back to the hotel by Taxi or Bus because they could not do the walking. Other than that I heard good comments from all my fellow travelers.
