i am planning a party at a farm for my 4 year old. we are clear on the costs of the children but it will be a joint party with my 2 year old and we imagine most parents will want to stay to supervise their own dcs. Should we be planning to budget for the cost of the parents entrances to the farm too or is it reasonable to expect that if we cover all costs relating to children the parents will pay for their own entrance? it will probably make a material difference to the number of dcs we can invite.....anyone got any experience of this situation?
