Sounds great! I hope the girls have a fun time, and I’d love to hear how it goes :)
If you’re looking for more guidance on GMing this style of game, I’d also recommend reading the DM guidance in Dungeon World. It helped me a lot in moving from D&D to PbtA games.
I will take a look, thank you! In the last weeks I've listened to GM podcasts and to some recorded live sessions. I've cleared my mind up a lot. Mastering PBTA games looks easier than I thought. So, now I have a second reason to organize the Hogwarts RPG session: as a birthday present for my daughter, and to satisfy my curiosity about mastering a PBTA. :-)
