I will be making my first trip to NYC for a professional conference the first weekend in May. I'm flying in Saturday and having dinner with a friend that night, and conference is Mon/Tue (departing Tue right after). Any tips on things to do/see on Sunday, or Monday evening? Getting around the city tips? Since NYC is more of a hotbed for dance than my homebase (understatement of the year), any suggestions there? I don't even know what you can and can't visit/go inside (e.g. Statue of Liberty, Ellis Island, etc). tbh, I'm not really interested in any 9/11 memorial stuff, in light of the limited timeframe. Thanks for any suggestions/hints/advice.
