NYC has three major airports, LaGuardia, JFK, and Newark. LaGuardia and JFK are going to be slightly closer to the venue, but all three should be relatively convenient and have several flights a day going across the country.
We are planning to have something for out of town guests on Friday and Sunday. More details will come with the invitation.
We have hotel blocks in two Brooklyn hotels--both a short ride from the wedding venue. There are many hotels in Brooklyn and all over New York City.
