On the middle top part of the island map is a place you can go and after searching for a little while you can find a duck with a ranger hat on. He will ask you to get wood to make tents and tables etc. you can bring him wood by using the ferry with a truck on it containing wood. After you get the necessary supplies, the ranger duck will ask you to bring campers to the island. You can do this by using the ferry and instead of bringing the passengers to the original destination, bring the to your island. They will stay there instead and leave a review after doing this a couple of times you unlock the ferry duck which can bring campers to your camp without you being there. If you put food in the cooler/chest thing you can earn money in the safe. Hope this helps! ❤😊
