Obrammergau has been on our bucket list and due to Covid it was postponed 2 years so we jumped on the chance to do both the Rhine and Oberammergau. There was a last minute switch to our ship from the Alruna to the Tialfi but we were told they were twin ships and it all went smoothly. Due to low water levels we almost cancelled but are so thankful we didn't! While our balcony cabin was on the small side, we didn't spend much time in it and the bathroom was wonderful! There was plenty of storage in our cabin too.
The meals were fine - nothing remarkable but nothing bad either. We did have a couple of times when the service was very very slow (like we were in the no serve zone).
The shore excursions ranged from wonderful to average but we did enjoy each one in its own way.
