We have traveled with Tauck on four previous land vacations and figured they would be just as good on a river. We traveled from Amsterdam to Budapest. Halfway, we had to switch ships with Sprit's sister ship, the Treasures. Kept the same cabin number. The Danube River was too low and we heard about other tour groups bussing to cities from a docked ship. Our ship had 78 tourists; our cabin was about 300 sq ft. This was great as we got to know almost everyone at least a little bit. The ship swap required a 3 hour drive after a city tour. Our Tour Directors made this fun with games, cookies, crackers, and wine on the bus! Highlights: A private dinner at a Palace in Vienna with 2 opera singers, 2 ballet dancers, and a chamber orchestra: a night sail on the Danube through Budapest - BEAUTIFUL: Lunch at Bruer's Rudesheimer Schloss with great music playing both German and American tunes: Sailing through the Lorelei Valley and the Wachau Valley (Rhine and Danube): Lunch on our own during free time in 3 cities (Tauck gave each person 20 Euros for spending money). The only extra costs we had on this entire trip were a couple meals as we arrived a day early and our souvenirs. You will never go wrong with Tauck. They PLAN for anything! and everything!
