The NYC subway has a bit of a learning curve, but it really isn't that bad. People are pretty understanding about non-locals being confused and will answer questions readily, and pretty much the worst case scenario is that you accidentally catch an express train, miss the stop you were shooting for, and have to go across to the other platform to go a few stops back in the other direction. Being unwilling to even try is just baby brained, especially for a "travel journalist."
Oh she's a "travel journalist" who almost exclusively does cruises and Disney resorts. That makes more sense.
