Flight
NYC has tons of airports, but Laguardia (LGA) is very easy for domestic flights and is only a short car ride away from the hotel. It is also worth checking out flights to MacArthur (ISP) as it is a similar distance from the hotel and you may be able to avoid (some) NY traffic, depending on when you arrive.
Hotel
We have reserved a block of rooms at the Melville Marriott and you can access the website through the link below. The special group rate is $179/night and we recommend you make your reservations as early as possible in case the block fills up! There will be transportation provided to and from all wedding events (Friday and Saturday night) from the Marriott. There will be a Sunday brunch included for all hotel guests as well!
