We normally drive around Europe but decided that a cruise would be nice and the Rhine river goes through a very pretty area of Germany. We were doing the two week trip from Amsterdam to Budapest. 15th October to 29th October.
Due to low water levels however the Rhine is currently not navigable and so on the second day whilst still in Amsterdam we were advised that a lot of the trip would be by coach and staying in hotels. APT gave us the choice of staying onboard or flying home from Amsterdam the following day with a full refund. We choose the latter and less than a week later we have received a full cheque refund.
It would also now appear that the Danube is very low and has been for some time so the latter part of the cruise from Vienna to Budapest would also be by coach/hotel.
