We were traveling with 3 adult children (in their 20's) and selected Avalon because of the general itinerary and the fact there was not a single supplement add-on for single rooms (which each of our kids had). On this itinerary, there were 3 nights where we could be "in town" to explore for dinner and bars (Amsterdam, Cologne and Rudesheim)- which as great. The shore excursions were good - though I wish the walking tours were 45 minutes (instead of 1+ hours) and we that were given more free time. We would often peel off from the walking tour so that we could have more free time on our own. (You really don't feel like you have been someplace until you have wandered on your own - and 0-45 minutes of free time just is not enough). We did a few of the add-on excursions - biking, Maginot Line, Alsace Wine Tour, Colmar. We also did the add-on of Luzern, Zurich and Como - which was a wonderful way to enhance this trip. Monograms got us to the locations, then lots of free time to spend as we please. Our kids were certainly a curiosity on this trip (there was 1 couple in their 40's, then everyone was 60+) but they loved the flow of wine and beer at all meals, the underutilized fitness room, snoozing and reading on the sky deck, and all the cities and towns they got to see. This trip offered a wonderful, stress-free and fun-filled way to spend time as a family.
