Wedding Reception In Hudson Vally NY

I am having a small wedding, about 60-70 people. I am having some difficutly finding a reception site. I am getting married in May and would like a Saturday night wedding. Many of the reception sites have a 150 person minimum. Does anyone have any suggestions for charming castle like places? I have looked at some mansions, but do not like that the dancing would be seperated from the dinner.
Thanks
