Japanese Stroll Garden in Mill Neck

I had heard that it was a lovely, quiet place for pictures and or a wedding. My FH and I have been looking for a place to take pictures that does not charge a lot of money. This place does not. However, my idea of a stroll garden was a bit different than what I found. This place takes a hike..and certainly not one that you can do in heels and a wedding gown. While there is a beautiful Japanese Teahouse that would be a gorgeous place for a wedding you have to walk uphill on what looks like cedar chips and across a log bridge to get to it. There are no flowers there, only plants, and it was incredibly humid. So my search for the perfect photo spot continues. If anyone has any suggestions or knows of any place where you don't have to pay a ridiculous amount of money to take photo's please let me know. I am running out of time!!!! Thanks.I am looking for something in the area of Oyster Bay (not Planting Fields..too much money).
