HELP: Need photo location 9-23-06

The place we are getting married at, obviously it's a smaller room, and there is a wedding in the main part, so we are not permitted to use the main grounds or main inside for photos

I am so concerned of where to take photos, especially if it rains.
Old Westbury Gardens is booked so that's out.
We are so far leaning towards the Nassau Museaum of Art and a local beach if it's nice.
What about if it rains?
Any ideas????
