Not sure what type of bungalow you are looking for (ie chassidish, modern orthodox, etc.) but I have gone up to vacation village for shabbos in the summer. It is 10 minutes from liberty. People rent their houses for the summer, I'm sure its not cheap but its a very nice area that is enclosed, has a lake, pools, basketball courts, all those types of amenities. They have a shul and full beis medrash as well.
