How it’s used
재미있다 means fun or entertaining, and in speech it is often shortened to 재밌다. Its opposite, 재미없다, means boring. For “interesting” in the sense of thought-provoking, 흥미롭다 is closer; 재미있게 보내세요 means “have fun.”
Common mistake
Saying 저는 재미있어요 to mean “I’m having fun”; it actually means “I’m a funny person.” Say the activity is fun (파티가 재미있어요) or use 재미있게 놀고 있어요.
