Ya - here clients are paying for the space whether they occupy it for before and after or the full day so if I am open and offering program they are welcome to come.

However I know people who offer before and after school care at a 'lesser fee' and than have another younger child who comes 9-3 so the space is 'occupied' during the day time and therefore the B&A children cannot come on PD or March Break or Summer closure unless the provider has 'space' open up for that child.

Depends on what you want to offer and so forth just make it clear in your contract to clients what they are being offered and expected to pay for!
