Unfortunately our tour got cancelled on Friday due to the weather, so it was moved to Saturday night. Needless to say it was still extremely cold, staying around 30 degrees the whole tour. Our tour guide, Daniel, was enthusiastic despite the cold weather and he did give us a lot of fun historical information. My girlfriend and I did have a good time, but we did spend a total of three hours outside. Be prepared to walk for most of that time, and definitely be prepared if you know it will be colder out. There were also children in the group, which I would not recommend as it was a lot of walking and there wasn't a lot of information that they would enjoy or find relevant. Overall, it was a fun experience, wish there could've been more stops, but I would recommend going when it's warmer out.
