I made a group rate to Mount Laurel for 2 years. It was perfect. They got bought and had new management this past year. Last years stay for midwinter was an absolute disaster. No room service. Dirty rooms/bed sheets on arrival, NO HEAT in many rooms, leaks in ceiling. Garbage in the can from previous guests. Nothing set up in dining rooms. Ice cold pool. I will not be bringing any groups there in the near future unless there is a change in ownership/management and they get their act together. In the mean time, I cant find a shabbos-friendly, good situation like that in the Poconos at an affordable rate.
I might end up renting a house in a rental are of Lake Harmony and have some families stay nearby for minyan. If I come up with something, i'll post on my chats and here.
And you also usually make an arrangement for shabbos in the Poconos, no? Very affordable.
