Do you want to visit (cruise in) Glacier Bay? Most Princess 7-day cruises go to GB. HAL has the 2nd most GB permits.
If the kids are expecting RCL water slides, etc., they'll probably disappointed -- too cool in Alaska.
Which ships have Kids' Clubs w/evening hours? Hopefully, the kids & adults will be busy seeing the beauty of outdoor Alaska in the daytime.
Please don't expect/plan to do all activities TOGETHER every time, every day! 15-20 people trying to move as one won't fit many places!
There is a PAGE on Cruise Critic devoted to Family Cruises.
The first of my 5 cruises to Alaska was 40 years ago with my small family.
ENJOY!
