“Who asked the Chosson or kallah in Belz or Bobov or any other chassidus when they making chassuna if they like to have such a big Wedding”
I’m assuming that the kallah knew that she was marrying the grandson of the Rebbe, so she probably had an idea that she was stepping into a big wedding. And I’m also guessing that the chosson and kallah had some say in the wedding plans. I don’t think they were blindfolded, brought into the tent, and then everyone yelled, “SURPRISE!!”
