Could I please have some ideas of what your turning-9 year old boys have enjoyed for their birthday party? He would be inviting up to 10-15 friends/cousins (mix of boys & girls). Flexible budget but not horrendously expensive.
It’s for a winter birthday so outdoor options aren’t likely to be popular (shame as a nature reserve near us does fab den building and campfire parties).
We’ve done trampoline parks twice so I’m looking for other ideas first before we revert to that. Also not soft play either as he has outgrown that sort of thing.
