I suppose it being colder there it'd be a double whammy. Being cold and stuck on a mountain sounds like no fun at all. Of course, when a Titan gets stuck on a mountain they just unstick themselves with comparative ease then stay warm in the process. (It's a Titan thing.) It's the same when a Titan gets lost...oh hang on, Titans don't get lost.
Seriously though, it's going to be a blast and the planning stage is fun too.
