My parents have done several of these. They’re in their 70s/80s, and my mom has limited mobility. They’ve been able to split up with my dad doing more active excursions & my mom doing ones requiring less walking. So I think there will be options for you.

I want to book a Viking European cruise (I’m thinking Northern Europe) but am concerned about the activity level. I can walk about 8K-10K steps a day and need to rest/sit every half hour or so. Are the excursions doable at this level of activity? Are mobility scooters or golf carts available? Please share your experience.
