We would like to decide between radiance, brilliance, or quantum class. We are open to anything and kids are old enough to really enjoy the experience of alaska and the excursions rather than the activities on the ship. But still want them to have things to do. We've been on all oasis class, odyssey, freedom class and navigator but none of the older ships. Brilliance is the least expensive - canada round trip. Radiance is the coolest itinerary but oldest ship and sails one way so we'd have to fly into/home from different airports. Quantum is the newest and would be a fun ship for the kids in the cold weather (we didn't love odyssey for our carribean sailing). Thanks!
