i am in my forty's and think hall is great. as don't want that always activity like carnival .like to feel like a guest not like a passenger. but lots still going on through out the day to keep you active .and obviously the shore trips in port lots of choice but a little pricey is norway so be warned.
also regarding flights if coming through the uk both ways you could try airline called easyjet web-sight is easy jet .com. they fly daily from copenhagen to london so you could come back on the day cruise ended or have a couple days in copenhagen your choice. they are no frills airline but have good reputation and fly all over europe and our a lot cheaper than the others , would think roughly $90 us for that flight to uk.
hope this helps and good luck with your research.
