[RBS] Looking for a place for a shabbaton for 50 people

Does anyone know of a big enough place to accommodate 50 people for a shabbaton, preferably with a pool if possible, anywhere in the country (besides North/South/Yerushalayim/RBS)? Looking for somewhere more out in the countryside, a moshav or something like that.

All the best,
