Forgotten Carnival

Your best childhood memories took place at the Grand Carnival. The rides, games and shows are still very fresh in your memory. Your grandfather, founder of the Grand Carnival, would take you there as soon as he had the chance. He dedicated his whole life to the Grand Carnival and carried it on his shoulders for decades. He was so proud of it. Unfortunately, for health reasons, your grandfather had to close the Carnival a few years ago. During your most recent discussion with him, an idea suddenly came to you. You are going to try to reopen the Grand Carnival! Nothing would make grandpa feel better! You then gather a few family members and put your plan into action. And since you might be entering the Carnival for the last time, why not take advantage of the facilities that are still functional? But don't waste too much time, because in 60 minutes, at midnight, the electricity that powers the Carnival will be cut off forever, making your mission completely impossible.
