Xpost: indoor/outdoor photo spots

I'm looking for primarily outdoor photo spots that have an indoor option (in case of a very hot day and/or rain) within a somewhat reasonable distance from East Meadow, although I can be flexible. I really only want to consider it if there is an indoor option since I'm sort of a pessimist and afraid it'll be 100 degrees out since we're getting married in August. ANY help would be greatly appreciated.

Specifically so far I'm really interested in the Hempstead House, although I've read some older posts on here and am unsure about being able to book the place in advance. Does anyone have any recent information on that venue? Any information on similar sites or comparable places with outdoor and indoor options are appreciated too!

Thanks!
