Yes Photo Driving Licences are accepted in the USA, and of course your passport. Unless you have a student/forces card, these really are the only two forms of photo ID open to most. You are frequently asked for ID when making purchases on your Credit Card in the USA, so its worth carrying something for these instances anyway.
I always have my passport with me and donÕt have any worries in carrying it around on my person, but your Driving Licence card will fit nicely in your wallet so if you have one if probably the more ideal form of ID to carry.
Have a fab time in NYC
