This long strip is the center of town and full of great options for shopping and dining. Walking distance from the Delamar and Greenwich Harbor. The Delamar hotel also provides a free shuttle to and from Greenwich Avenue.
Also walking distance from the Delamar Hotel and Greenwich Avenue, this is a beautiful park with tennis courts and plenty of space to walk/picnic.
Island Beach is an incredible public island that is accessible via a ~5-10 minute ferry ride that picks up right next to the Delamar Hotel. The tickets are unfortunately only available for purchase online from Monday-Friday 9a-1p at the attached link but I would highly recommend buying ahead of time as it is a great way to spend the day.
The listed phone number is for the Delamar's experience manager who can coordinate a boat rental for small groups. You can take the boat around the Long Island Sound and (hopefully) catch some sun before the ceremony begins.
