Share Costs for the Hartwell Family Reunion

The Hartwell family reunion organisers are surveying adult relatives about sharing costs for a weekend gathering. The hall requires a deposit, and meals and activities must be booked ahead. Some relatives can attend the whole weekend; others can come for only one afternoon. One equal payment per adult would simplify bookings and cover every event. Alternatively, adults could share the hall cost equally and pay separately for their selected meals and activities, requiring earlier individual commitments.
