Managing group events and family activities in a community setting

[Areolah]

Hi,

I’m thinking about how to organise events for families, like group stays or retreats, with proper management of participants, kids, and different activities.
In these situations, what do you usually use to manage registrations and participant details? Especially when you’ve got different profiles (adults, children, specific needs, etc.).
I’m also wondering if there are tools that make it easy to track contributions or participation from each family, particularly when there are multiple payments or special arrangements involved.

Ideally, something structured enough to avoid mistakes, but not too heavy to manage on a day-to-day basis.
