Last year it stormed pretty bad when we went to AK......Yes, we were a little cold, but honestly we just kept on going, and had a wonderful time. The park virtually cleared out of everyone and we had no wait times....rode the safari 3 times, all the animals were out. Went on Kail, what the heck, we were already soaked. We had on tennis shoes but once you are wet, you are wet, so may as well make the best of it. It was the best day we had there. Plus with the overcast skys, your photos will turn out great!!! One of our favorite photos is of us, wet to the bone, but with big smiles on our faces in the empty animal kingdom
