"Older" anything is a relative term, right? I've been on 3 cruises, my first was just before I turned 52. I'm registered for the Puerto Vallarta trip in late October and I will be 58 years old. In my opinion, the average age of "Solo" travelers was about 45, and the average age of all travelers was more like 55. That's the cool thing about Olivia trips, age doesn't matter - everyone has a blast!
