We really enjoy Princess, even more so because we can drive to the closest port of San Francisco. And compared to RCI, Princess really knows how to offer up a comfortable mattress. So comfy. My last three RCI cruises the mattresses were ROCK hard. They couldn’t put enough extra padding on my side of the bed to make it feel soft enough. That said, for a family I’m sure a Royal Caribbean ship will have plenty of fun activities for all age groups. They tend to have all the super slides and rock climbing walls as well as other water activities. As for Alaska sailings, Princess owns Alaska! They really know how do it right. Since it’s not really a warm weather itinerary, I don’t think many of those outdoor water activities would be beneficial, anyway. They still have plenty of indoor fun for the kids at their kids clubs. To me, Alaska IS the fun! If I had to choose a cruise line to Alaska my preference is Princess. In fact. We had a 10 day sailing out of San Francisco booked during COVID but had to cancel. One of these days we’ll book it again! Next up is an RCI sailing to Canada/NE and then back to Princess for the British Isles. Awww….a soft and comfy mattress once again! 🙂
