Local Attractions for OOT Guests?

Hi Girls,

Our reception and hotel are out on East End and I am trying to come up with some fun ideas for our MANY OOT guests to do (wedding is Saturday, they have Sunday and potentially Monday as it is a holiday weekend).

So far I have

LI Wineries
Briermere Farms
Lewin Farms for apple or pumpkin picking
Tanger Outlets
Montauk Lighthouse (for those brave souls up for the drive)

Any other suggestions would be great!!!

TIA!
