I travelled with two friends after my recent retirement. After making all arrangements I broke my ankle in April. So I went in cruise in a boot. Not optimal but I made it work. I only had to cancel one excursion. I can’t say enough about the entire staff. They were excellent, pleasant, informative, helpful, always cheerful and made sure if our comfort. Rooms were kept up. Food was excellent and restaurant service great!. I left my cane at home and needed to buy another the concierge found a store in Vienna and made arrangements for taxi for me. Excursions were fun and well organized. Guides were well versed and entertaining. If I wanted anything different, a more precise description of the amount of walking/distance and terrain would have helped. The F busses helped for the group that needed a slower pace. Concierge make leaving and returning to ship easy. Helpful when we needed change €.
