Go to Granby Zoo or Safari Park

Hello, this summer my sister-in-law and the children, that is to say my niece and my nephew, are going to go either to the Granby Zoo or to the Safari Park and like last year my sister-in-law asked me if I wanted to go with them. I know you will probably say yeah but the entrance to the Zoo or the safari park doesn’t cost an arm and a leg. For me it’s still expensive… Plus you need some for dinner there… Thanks in advance.
