Use booking language that reflects the people attending and their caregiving roles. Allow for grandparents, single adults, siblings and other agreed caregivers. Ask for the information needed for care and accommodation without imposing one family shape.
Use registration language that allows the people actually attending. “Adult one,” “adult two,” “child,” and “authorized caregiver” may work better than assuming a mother and father in every booking.
Do not assume that the person paying has legal authority for every child. Record the required permissions and authorized handovers through a reviewed process.
Plan for single parents, one adult with several children, grandparents, blended families, foster or kinship arrangements, and other households without making them explain private circumstances in public.
Ask about access and support needs for each person. A family may include a toddler, a teenager, and an adult with limited mobility. One “family fitness level” will not describe them.
Offer activities where success does not depend on having two able-bodied adults. A game that requires one adult to supervise a baby while another joins the child excludes some households by design.
Be clear about the minimum responsible-adult arrangements your actual program requires, based on law and safety review. Discuss individual situations respectfully rather than inventing a rule at arrival.
Your task: Test the whole program with a one-adult household and a multigenerational household on paper.
