Our Wind Surf Med. cruise probably had few ports in common with X. For Barcelona, use your feet, the subway, buses, and the arial tram, and do the city on your own. In Villefranche, we spendt some time wandering around the city, then took a great ship's excursion to St. Paul de Vence, where we placed a stone on Marc Chagall's grave. That's an old Jewish custom, and the arrangement of the stones for Chagall was itself a work of art.
Fed. Reserve for Euros? You've got to be kidding. AAA sells Euros and Euro traveler's checks. both in their offices and online. Our bank is Bank of America, and we used ATMs in France (Paribas Bank) and Barcelona (Barclay's) with no bank charge, since we used correspondent banks of Bank America. We could have ordered the Euros at our bank branch or online from Bank of America, but the cost would have been high.
