That should work better since the child will be there while the group is awake and busy doing activities. The issues will be them getting him there on time so you aren't just hanging around waiting for him so you can start programming or go to playgroup or whatever. The other issue will be making it clear what time they are paying for as far as pick up goes and what the fee for being late is going to be and that is regardless of what time he arrives. There is nothing worse than waiting for a parent to pick up before lunch and others are needing to eat but you feel guilty serving them or pick up after lunch and you are waiting with cranky children that need to be put down but you know the confusion at the door will wake them up.

Having had the warning and told why they will only have themselves to blame if they screw it up and lose their second chance.
