We took parents on the cruise who are 85 and 86 and they enjoyed many aspects of the cruise. For us younger folks this was a bit of a burden because people in their 80's require constant attention like children and teens do.
For the seniors in our group there were many activities they could sit nearby and watch, and a few they participate in.
The restaurant service was good for the group with many different choices of food. We did not like the under cooked scrambled eggs served for breakfast. Under cooked eggs is very unhealthy for persons of every age so who ever thinks its a good idea to serve under cooked scrambled eggs is a IDIOT!
Ship docs in navy base and you take transportation to Key West. In KW its so hot and humid its difficult to enjoy anything but a cold drink or treat.
We did our own excursion and we found out most of the down town travel/shopping areas recommended are a waste of time.
