Hello, I will be in Anchorage one night after a cruise/land tour. My flight doesn't leave until 7:30pm the next evening. I would like to take a tour, thinking Turnagain Arm. Most of the tours I'm finding is afternoon tours and they also require at least 2 people. I will be by myself(50's female). I found a shuttle I could take, where I can get on and off. I would rather do a tour being by myself, but if I did the shuttle would it be safe?
