Does this sound like a fun idea for a sixteenth birthday party?

My parents really want me to have a party, but I honestly don't feel like handling all of that planning and whatnot. However, I want it to be a little more than having three friends over for a sleepover. I was thinking this: My three best friends and I choose partners and go take a ballroom dance class. After that, we go to dinner and my girlfriends spend the night. Does that sound like fun, or does that sound lame? My friends are all pretty classy and not into the whole party scene, and two of them are pretty into dance. I just want to make sure the guys don't think it's boring or anything. What do you guys think? Any alternate suggestions are welcome.
