I have been to NYC a number of times and love it! Used to go regularly to watch the Jets play the Dolphins and later just for the fun of it. Never been there at New Year though.
Going counter to the crowd. I have visited NYC twice in the last 4 yrs. Saw JoMo both times.
2012 - Thanksgiving (4days). Stayed at the Hilton on 6th Ave, watched the Macy's Parade march by in front of me. It was spectacular. Went to the 911 Memorial, visited Deli's and saw "Wicked" , wife and I had a great time.
2014 - Christmas (a week). Stayed at the Millenium Hilton near Memorial and Battery Park. Visited the 911 Museum, Liberty Island. Then went up to Broadway area at the Hilton Garden Inn. Saw 2 Musicals, 3 plays and ate at a number of great restaurants. Had Christmas Brunch at Bryant Park Grille, went to Top of the Rock and visited Chelsa Market where the Cooking channel is located.
Dirty? Not like it was back in the 70's
Expensive? Yea, and so it California, Chicago, Key West and a ton of other destination locations.
Rude People? Not my experience. I would everyone to be fun and accommodating and even made new friends.
Lots of People? Yup, but that is to be expected.
So, while it might now be everyone's cup of tea or 'shine, I found it exciting, new and different. I am sure I'll return to NYC (Manhattan) again.
