Veendam draws primarily North Americans, but most sailings also have a nice international mix of Asian, Latin American and European travelers as well. Look for couples, many of which are retired, and a handful of younger cruisers that are often with larger family groups. On European sailings, you'll notice a change in passengers with more Europeans, but still an overall older demographic, with most people over 60 and a fair amount in the 70+ range. Summer, spring break and holidays bring a few more families with children aboard, so plan accordingly.
