I sailed on the Norwegian Sea in Jan 99, and found her a nice comfortable size ship. Different itinerary completely, so I can't answer to that. Enjoyed it a lot; food is not quite as good as some other cruise lines but unless you're really fussy, it should work out fine.
If you want to meet people, be sure to go on some shore excursions, and ask for a large table for dining (I assume that's an option with Freestyle dining, which I haven't yet experienced.)
One thing to be aware of, there may be some vibration during meals in the dining room at the stern, especially when leaving or entering a port. Nothing to worry about, just a little unnerving if you haven't experienced it before.
Approach people, ask to sit with them at meals or shows or lounges, and have a wonderful time!!!
