Flight
New York has three close airports and many domestic flights each day. Newark definitely has some of the cheapest flights but is farther from the city, about an hour drive from Brooklyn. JFK and Laguardia are both about 30 minutes away by car. Bus and subway routes are also easily navigable!
House Or Rental
New York has amazing Airbnb options all around the city, many with multiple bedrooms and kitchens. The wedding is in Clinton Hill, Brooklyn near Fort Greene Park, but there are lots of fun neighborhoods nearby worth exploring like Williamsburg or across the bridge in Lower Manhattan.
Hotel
There are so many hotel options in and around Brooklyn. Hotels near Fort Greene Park will be very close to the ceremony, but options in Williamsburg, DUMBO, and Lower Manhattan are only a subway stop or cab ride away.
Train
If there is a subway stop near your hotel or airbnb you can easily get around the whole city! The closest station to the wedding venue is Clinton-Washington Avenues Station on the G train.
