Unique Christmas Venue

It is super important to my FH and me to have an unique and beautiful Christmas wedding venue on LI. We had toyed with the idea of a FL wedding but logistics and convenience factor for out-of-town guests just made it too difficult. Any venue ideas would be greatly appreciated! So far, we have looked at the following:

Watermill (OUT)
Lands End (Probably OUT)
NYIT de Seversky Mansion (Love it but $$)
Flowerfield (MOB loves but I'm not quite sure..)

And we are going to schedule an appointment for The Carltun


PLEASE HELP! I'm so stressed out and I feel like this isn't how you should feel when planning the happiest day of your life..
