I love the Islip Grange and have no idea why it isn't more popular for smaller weddings. I married a couple there almost 4 years ago it is quaint beyond belief and totally affordable.
It is a Town of Islip Property and if you call Annette at 631- 224-5684 she'll send you out an application and set you up with one of the care takers for a look see.
There is a $100.00 security deposit which you get back by leaving the site as you found it.
The 3 hour site fee is $175.00 for non residents and $125.00 if you live in Islip. Photo's ceremony what ever you choose to do with your 3 hours is up to you.
Occupancy is about 60 people and they did have an organ there.
For those of you who have never hears of the Islip Grange below is a link with some photos.

Wishing you both many healthy years of love and marriage, wisdom and wonder.
