Pues, realmente no hay mucho de differencia. Cuando se dice "in the park" tiene el punto de visto de estar adentro del limites del parque, pero cuando se dice "at the park", el hablante tiene el punto de visto de estar afuera del parque. Lo mismo cuando se habla de la universidad.

People will understand either way but usualy you would say "there are swings AT the park" rather than "IN the park" but you would say "I like to swing IN the park" rather than "I like to swing AT the park. For the university I would usually only use IN for directions. "I take art at the university." "My art class is in the university."

"At the park" is much more common, especially now that "where u at?" is a popular phrase. "in the park" is usually a specific direction when someone needs to know where you are specifically at, if that makes sense to you...But really you will be understood either way.
