Travel any chance you can
Another one off my bucket list in 2012. We were very fortunate that we were able to take a River Cruise this summer on one of Viking's new longships. We enjoyed it as it was very port intensive (no sea days) with city and walking tours included. There was also ample time to explore on your own after the tours. Most of our fellow passengers enjoyed the cruise but a few did not as they preferred the entertainment, pampering, variety of bars & restaurants on ocean cruises. River cruise boats are designed to fit through the many locks (we went through 66!) and low bridges which leaves no room for gyms, spas, casinos and the many entertainment facilities found on the large ships.
Food was plenty, open seating and lots of buffets specializing in local cuisines. I gained 5 lbs. despite all the walking we did. Attire was pretty casual except for those that wished to dress up at dinner. Passengers in general were well traveled and interesting.
