We would not be concerned. All of GCT's European River ships, except for the Russian and South of France ships, are basicly the same except for passenger capacity. The cabins are the same and the common areas are very similar except for size. These 2 ships are, in fact sister ships, with the same capacity and layout. It is possible that the Harmony required longer off season maintenance and was not ready for the start of the Holland cruise schedule, causing a reshuffle of the ships schedules. We have been on the Symphony and Aria, and if you didn't look very carefully, you would not be able to tell the two apart. We are also schedued for the Bizet in March, which is smaller than the others, but still almost identical.
