Having just returned from 14 days on Quest this week, I can share a few observations. We had 420 +/- pax. 336 from the US and the rest from 15 other countries. I'm 72, reasonable fit and agile. I was surprised at the number of scooters, wheel chairs and rollators (walkers) in use. Ages seemed to skew a bit higher than myself, but we thoroughly enjoyed the company of everyone we either dined with, met on an excursion or met having a cocktail, regardless of age. I think the 6 sea days and Panama Canal being the main attraction would lend itself to an older, less mobile group.
