1. Who is coming?
2. Shared costs, and who fronted them
The house, the boat day, the grocery runs: anything the group shares. Costs each family pays only for itself stay out of this.
3. How does your group split?
No right answer, but decide before the trip. Even per family is simplest; per person with kids at half is the most common "feels fair" pick for mixed size families.
