I've sailed twice the week after this one. Our 2017 cruise was rainy, with rain almost every day except Ketchikan. Our 2019 cruise was sunny and warm the entire cruise. The pools were as busy as any Caribbean cruise I've been on. So, I guess I'm not very helpful. What I will say, is that the rain did not detract from our cruise at all!
On our 2017 cruise, we did the Bear excursion in Ketchikan. It was really great and we saw so many bears. We walked on an elevated walkway over a river and the salmon was running, so bears and eagles were busy feeding
