Quiet grotto and relaxed performance are they for all people with ASD?

Myself and my husband have taken our Son to both a quiet grotto and a relaxed performance. He loves shows if he knows the story and characters or the atmosphere is very lively full of fun and upbeat.  The relaxed performance he didn’t know the story so he was restless, it was nice but not full of energy. . He likes to see Father Christmas and has done before in aquiet grottos with fairy lights,  he went to one with no lights and hated it.
