We returned from our cruise the 28th after setting on the river side for 6 days in Dresden. We were also told we were a days rain away from cruising. I think it would be critical that rain fell in the Prague area for the boat to cruise and I couldn't guess how many days would be necessary. GGh, did you pay extra for the view of the weeds too? No concessions whatsoever. Not even a glass of wine. The cruise line verbally offered 1/2 half off a future cruise which, frankly is of no value to us.
