But the OP asked about "Holland" rather than "Holland America Lines"
The original poster also stated that English was not their first language... so it wasn't that "helpful" to try and "joke" at their expense.
As for Holland America's demographic..... though slightly higher than some other lines... on their Caribbean itineraries you're likely to find an average age for passengers to be the 40s.
Last year when I sailed the Westerdam in the Caribbean, on our particular sailing the average was actually considerably lower than that.
Norm.. sometimes I think you spend too much time tossing out "old reputations" rather than researching more current opinions and experiences.
