Your itinerary requires alot of tendering. With 2650 passengers on the Konigsdam, it may take awhile to get ashore, not a pleasant option. Just remember, the passengers on longer cruises tend to be older, but even older if it is a round-trip cruise. With a larger ship, you have more activities though this could be offset a little bit by an older less active fellow passengers. My biggest strike against the Konigsdam is that when you think of Tahiti, you are really thinking of Bora-Bora - the Konigsdam doesn't go there - it is too big. Food is much better on Oceania though the entertainment is better on Holland America. So, Oceania would be the better choice unless you like to be on a really long cruise or you hate flying or entertainment is very important to you.
