I thought this too. My parents don't mind doing their own thing (and my inlaws as well) but they have each other. Personally, I wouldn't mind doing things by myself, and I have in the past, but not everyone would feel that way, esp a senior with hearing problems. OP, I would say don't change all your plans to suit your mother but I wouldn't abandon her 100% either. It's impossible to do everything in 1 cruise anyway. Heck, we've done 13, many were 7-nights, and still there's things we haven't gotten to. So don't feel that if your mom wasn't coming, you would see/do it all. There's never enough time.
