I'd select by the itinerary that most interests your family because AK is definately more about the ports and scenary than it is about the on-board experience.
Personally, we prefer a north-bound one way (flying back), but if you find a round-trip that you like it is also a wonderful choice. RCI Radiance-class ship is pretty much made for an AK itinerary. We've been on several Radiance cruises out of Seattle and did not notice any fewer kids on board (cruising during the tradition school summer break your LS should have plenty of kids her age on board). Celebrity Solstice would be another great choice (Fire & Ice - the Hot Glass show in conjuction with views of the glaciers
). We've also done a Princess to AK - also very nice.
Many people get into the Glacier Bay vs Hubbard Glacier controversy. I think they are both wonderful (awe inspiring) and so I don't get hung up on that. Out of Seattle either a Vancouver or Victory or both are going to be offered -- check out the sites in each city and see what interests you. Ketikan is nice, Skagway has a wonderful national park service place, I really like Juneau. Sitka is my favorite - National Park, Russian catherdal, raptors . . . but few itineraries include it.
