My family went to Highland Park in Woodridge, NY for Shavous+Shabbos. We had a fabulous time! We got two bungalows that were big, comfortable and clean! We brought up our own food (the bungalows have a fridge, counters, sinks, stove, oven, cabinets and tables and chairs, couch) but they do have an option to get food from them.
There were plenty of people and kids to play with. Bring up a couple of balls and you can play elimination the whole Shabbos! They have a number of basketball courts and hardball courts. They also have a big bike that seats a number of people (I think eight). Everyone really enjoyed themselves!
Towards the summer the pool will be available (I think).
From what I heard, the price was very good.
