We have been on many tours with Smartours, but the Rhine River cruise was simply unacceptable for us. The river boat was so short-handed, that meals often last two to three hours. The breakfast buffet was in such a tiny area that it was often impossible to work our way through the crowd to get an adequate breakfast. All the tours were walking tours, which would not have been so bad, but long distances were covered without potty breaks. It is such a shame, because the cities that we visited were very nice, but we couldn't enjoy them much will all the problems we had.
