Yeah my parents (well mom anyway) are happy to do the tours offered by the cruise line, partly because it's all done for them and if there are any issues they will hold the ship for them. Mom is a bit nervous about being left behind.

It's kind of a big complicated family trip with my aunt along too, so there are three people in their 70s with some minor mobility issues, then my sister and her husband and I, all in our 40s, and my nephews who are 12 and 14. Us younger folks are a little more up for adventure and the DIY route. I'll try contacting AC and see what they say.
