Although not the case with all camps, many premium day camps choose not to operate on the 4th of July.  Unfortunately, another common practice is to charge the same tuition fee for the abbreviated week. 

Similar to multi-week minimums, this policy is a benefit to the camp only.  It allows the camp to decrease their available services to the customer while increasing their bottom line for the week. 

At The MLDC, we operate on the fourth since many parents are still in need of child care services. Otherwise, if we have not provided the service, then we certainly will not charge you for it.
