HELP! LI Mansion questions for a John Anthony's bride!

I am a John Anthony's bride and now I am considering changes places for my reception. I am thinking about a totally different style, but I have no idea what the cost is of these mansions on Long Island. If you know any cost/what it includes for any of the mansinos on LI that host weddings I would greatly appreciate it. I am already drained because I do not feel like starting this searching process again! I was done with that!

Thank yo ufor your help!

I hope this helps...

I just got married at the Vanderbilt Mansion and it was wonderful. Its owned by Lovin Oven Caterers, who have a great reputation for food and service. I recently wrote a review and posted pics. I'll FM you the prices.
