Even JW's are talking about no need for a kingdom hall using 4 hours in a week.
Wow! Excellent point! Think of the money member shell out on a monthly basis just to be used 2 days a week for 2 hours a day. Even with 2 congregations meeting in the same Kingdom Hall it doesn't make fiscal sense.
The American evangelical "Disney for Jesus" churches have activities going on inside their jumbo churches 7 days a week and all hours. Whether it is services, Bible classes, social activities, etc. The Watchtower would never allow that!
