First, design at least five roller-coasters and save the designs. Then start a sandbox park. Name a peep Sam Denney, then place your roller-coasters down. Also place a few food, drink, etc stalls, then watch as it becomes a successful roller-coaster park, and you can add more coasters but they won't ride anything else.
