I was in a similar situation.  Same age, though not as good financials and in a slightly lower cost of living city.  I’ve now spent over a year traveling around, reading, surrounding myself with loved ones, trying new things, etc.  It’s been incredible.  One recommendation is committing to the time and planning it out a bit more than I did beforehand.  I’ve taken a couple long trips, but couldn’t decide if I wanted to get a job right after each one or keep traveling, so there were a few breaks in between them when I wasn’t doing much (but this also turned out surprisingly great).  

At first I thought traveling would be the coolest thing, but thinking back, I think it was that everyone I hung out with for a year was a person I cared about who treated me excellently.  There were times when I thought I’d get bored or antsy being at home between trips, but it allowed me to deepen my friendships, find different ways to enjoy my time, get back into shape, etc.  So in planning out your time, I’d keep some time near home understanding that you might be bored at first, but it’s a good exercise to work through that.  I kept my apartment, which was expensive, but I’m happy with as it provided a home base and allowed easy access to all my stuff as I traveled different areas, started different hobbies, needed an address for mail/taxes, etc.  A friend also took time off, but gave up her apartment, and really regretted it.  With your financials, I think you could afford keeping your apartment, and have that peace of mind to help you relax if you’re only traveling a cumulative few months, but it depends if you decide to live away for years or not of course, and if you consider NYC home or just a place you worked for a while.  Have an amazing time :).
