Find out gender before reveal party or nah?

I have a question for any of you ladies who have done a gender reveal party, did you find out the gender before the party and help plan it or did you let someone else take care of it and get surprised with everyone else? I'm pretty sure I'll have my anatomy scan in February sometime and I already feel like I'm having to wait too long and I'm dying to know but I really want to be surprised with everyone. I didn't do a gender reveal party with my first so I'm in the dark here. If you can list some pros and cons also it'd help ease my mind. Thanks ladies!
Oh also, my boyfriend plans on finding out at the scan so I feel like I'll know based on his reaction because there is one gender he is really hoping for and has his heart set on.
