Depends what party. For example, right now, I'd say no because I'm stuck in a town for the summer in which there's nowhere good to go. My "friends" here who I am beginning to tire of, often insist that "it'll be fun" and it won't be.
However, if I had somewhere good to go, I'd party. I can play games any time, although I go out regularly when I can, I'd rather not miss out.
Ultimately, it depends on two things; Where I'm going, and who with. Some places are more or less guaranteed good, and some people have a habit of dragging you to parties that are basically horrible, and most annoyingly, trying to convince you it's fun, like they need you for some reason, and are trying to convince you to change what makes you happy so they can hang out more.
