Newly Engaged and new to this site

Hi All...I am newly engaged and have begun the process of looking for a venue and setting a date. I had originally wanted a destination wedding but I have decided to keep my options open and am also researching venues here on Long Island. I am going to be making appointments to view some venues and just wanted to know if anyone had any information/pricing on:
-The Watermill
-The Riviera
- The Bellport Country Club
-Giorgios

Also, if anyone knows of any other places that are nice and are waterfront, please let me know. Thank you in advance.
