Last year on our Empires Med cruise there were 2 tour groups: 1 of 30 people and another of 40 people. None of them were over 30 years old. The rest of us were in the 50-70 range. We've done 2 cruises since then and it's pretty obvious that Viking is trying to cater to a younger demographic. Rightly so I suppose. Maybe it depends on the region. Lots of muscles, muscle shirts, bikinis and speedos.
