I am a NYC wedding planner and i saw your message -
I am unsure if you are looking to get married in New York City in Manahattan? ive based this info on the city if it is not then i apologise! :)
if you are looking for a lovely location in central park the perfect place would be the Ladies Pavillion http://www.centralparknyc.org/visit/things-to-see/great-lawn/ladies-pavilion.html it is my favourite place in CP and is perfect for 10 people. Plus it is covered so it will keep you dry if it rains! lots of great palces to sty Nearby - depends on your budget but a great little hotel is the Park Central - couple of blocks from the park, also the Flatotel is great too. There is so much choice for restuarants! let me know what type of food you are looking for. I have lots of info on officiants, flowers etc. check out my work at www.iplannewyork.com - but happy to give you recommendations no problem!!
Cop Cot in Central park is a lovely setting and appropriate for a small party. It overlooks the pond and has a wonderful--and huge--granite outcropping behind, just perfect for photos. There's also a similar but smaller gazebo-type structure elsehwere in the Park.
