I have a fused polio ankle. My husband has occasional balance/ walking issues. We chose this itinerary because Viking has an included level 1 excursion included at each stop. This means few steps, fairly even walkways, handrails, not too many cobbles. There were a couple of stops that were involving a more difficult way to get to the coach, especially because of the tides, docking positions, etc. In those cases there were complementary shuttles. The staff were always quick to offer an arm to help move up ramps, move onto tenders, etc.
There were often free time periods on coaches of at least an hour. If I did not want to get off to shop, we were allowed to stay on board the coach with the driver. Some days I had more foot pain so I opted to sit and rest.
The Viking Venus is well laid out. We had a cabin near the center of the ship. We were close to elevators to take us to the World cafe on 7, our favorite restaurant. We were just a few doors down from the laundry facility. Any extra fee to be close to the elevator area is worth it.
The cabin is compact but every inch is so well used to provide storage for clothing and personal items. The beds are comfortable with a duvet. The AC/ heat control is in each room. There is a balcony with a table and 2 chairs with a sliding door. There is a desk which contains a mini bar fridge. The bathroom is perfectly laid out and roomy. The plugs and connections for charging a fitbit, computer, cell phone, etc meant that I did not need to use an adaptor. The night stands have all those connections. There are light switches to have a low light to the bathroom, another for the bed reading light, and a 3rd for all the room lights.
