I live and work in NYC (and I’ll be on the Jan 2nd Getaway cruise) and I am not worried. I also haven’t heard anything about a heightened threat alert and the Firm I work at and the building it’s located in keeps us appraised of anything like that since we are near Times Square. There have only been warnings/info about the ongoing protests and possible road closures. No heightened security in the subways or the Times Square area. I’d say areas of Manhattan are 1000x more likely (probably even higher) to be a target than one of the many, many cruises that depart from NYC regularly. But honestly it doesn’t matter what anyone here says, unfortunately if your son feels a certain way I highly doubt the word of random people on CC or NYers will change or ease his mind.
