It's not as simple as "people like to go where parks are". Some parks will thrive while others are abandoned, and it depends largely on the surrounding neighborhood. If you have a thriving neighborhood with people and businesses and things to do, then introducing a sunny park will make it better. If you have a cluster of office buildings and parking lots with no one living there and no theatres or recreation, then a park will just mean there is even less to do there.
