We selected the Romantic Danube cruise as the first river cruise because of the destinations. Also we booked with the anniversary discount of free air and the Silver Spirits package.
The weather was perfect, we even had a couple of days in the 70's.
We were thankful the river levels were up enough that we did not need to do any ship swapping or long trips on a bus. All the included excursions were perfect for what we wanted since this allowed us more time to explore on our own. We average 8 to 10 miles of walking at each destination.
