Renting the synagogue hall for an event not according to the rules
Question
Shalom.
The synagogue has a hall that it rents out for a certain price, and to synagogue members for half price. A family in which one of the brothers-in-law is a member of the synagogue rents the hall every Shabbat HaGadol for a family bonding Shabbat. One year, after they had already signed a written agreement with the synagogue to rent the hall (at the member price), one of the granddaughters became engaged and it was decided to hold the Shabbat Sheva Berachot on Shabbat HaGadol. May they change the purpose of the event from a bonding Shabbat to a Sheva Berachot Shabbat when the bride’s parents are not members of the synagogue, or in such a case must they pay the full price? It should be noted that the grandfather, who always pays for the event, will also now participate in the costs, and the brother-in-law who is a synagogue member will also participate in the event, but the pattern of invitees will be different from usual in that not all the grandchildren will come, and on the other hand there will also be guests from the other side.
Answer
Shalom u’vracha.
You need to ask the synagogue gabbai.
