Islandia Marriott for a reception?

Hi, my FH and I went to the Islandia Marriott 2nite to see about having our reception there. Seemed to work out good due to the fact of room availibility. Was wondering if anyone has done anything similar and how much it cost them. They range from 85-95 including tax and grat.
Thanks

There are other places that are in that price range also?

Thank you. Could you let me know where in Suffolk Long Island?
