I know it might sound weird, but my friend did this, and they loved it.
How about an old-fashioned kids party? Bouncy castle, kids food (sandwiches without crusts, jammy dodgers, lollipops, chicken nuggets etc), pass the parcle, retro music and dressing up. Admittedly my friends party was slightly older when she did this, so your daughter may not appreciate it.
Or, as I did last year, for my birthday, a "pink" party. They all dress pink, pjs, fancy, or whatever, and all food/drink is pink themed.
Or hire a karaoke professional (and get yourself some headphones lol)?
Hire a dance instructor to do salsa / similar lessions?
If she and her friends really high maintenance types, hire a recording studio?
