Check out these websites if you are interested in doing other things around town. We highly suggest checking out the Montauk Lighthouse, fishing on a charter boat, shopping in the cute boutiques in downtown Montauk or East Hampton, and spending time on the beach (even though the weather probably won't be warm enough to have an actual beach day, you could still take a walk or have a picinc). In Montauk you can access the public beaches from downtown.

The Eastern-most place on Long Island. Has beautiful ocean views on all 3 sides, a museum, you could climb the tower, and visit the playground. There is beach access as well.
Here are some of our favorite charter boats and party boats.
We LOVE to go fishing! Chartering a boat is one of the best ways to support the locals.

If you are coming with kids, this is a fun indoor playground your kids will love! We have gone with our nieces and nephews, we played the whole day and could barely get them to leave. This is a bit of a drive though, so plan accordingly. From the Amagansett area it could be about an hour depending on traffic.
