Danube river tour is what we booked thru Viking for Dec. This may end up being a bus trip instead, due to water levels. We wanted to know about hotels, meals, tours and itineraries? What sort of refund are we looking at for having to sit on a bus and packing/unpacking everyday. most of us on these cruises are seniors and we bought the cruise for the ease and comfort to see Europe, not lugging luggage. Please share your experiences on what to expect.
