Presently we are on the Viking Hervor sailing to Cologne (will dock at Vons for bus into town) and, last evening, were told Sunday we would be in Koblenz in the morning, sail the castles in the afternoon and arrive in Rudesheim at about 5 pm!!! The trip to Kinderdike left earlier than the original schedule to give us extra time to sail to Cologne! Have to hand it to Viking - they are really trying to deal with low water problems while giving us the most they can!!!! Will report back on how things work out Sunday - fingers crossed!!!! (BTW - the Herfor is new state of the art ship and fabulous!!)
