Fave NYC travel channels: HereBeBarr, TomDNYC, Travelling Clatt (his older videos), ActionKid, Sarah Funk (her older stuff, her newer stuff seems more geared towards more rich tourists), Cash Jordan (he focuses on apartments but still interesting) It's History (they have an NYC playlist)
Broadway channels: Billy Hipkins (for more insider stuff), Amy Lovatt, Broadway By Ghostlight (altho I wish he would tone it down with the mile-a-minute references and let the subject he was talking about shine through), It's Chris Smith Time, Schaffrillas, Musical Hell, Micky Jo Theatre, The Drama Dorks, Wait in the Wings, One Man's Opinion
