Missed 3 flight connections because Viking did not allow enough time between flights. Stuck at one Lock for 3 full days. Spent over 25 hours on busses and missed 4 tours as a result. Had to repack to change ships. Under-staffed. Service was average at best. Rooms not made up before 12:30 PM on multiple days. Poor time management, would often be 2 hours longer than told on bus trips. No exercise options, not so much as a treadmill, and even the short walking track was closed over 50% of the time. Have cruised 45 times but this was our first river cruise. Never again on Viking!
