Reading the various excursion descriptions, it looks like "strenuous", which I would normally overlook, is normally do-able by a reasonably active 70 year old and not at all the sort of high adrenalin event that the tag might suggest.
I can understand the need for a warning and that, maybe, the average cruise guest is of "mature years" and everyone is different, but how realistic are the descriptions?
What are your experiences of this?
