Anyone know about Florida's Pre VPK program (free preschool)? I have a question.?

My son turns 4 in late August so I have let his day care know that I would like him to start Pre VPK (Florida's free preschool) there in August. So I went to check him in to day care this morning and it said he has been moved from the 3 year old room to the Pre VPK room and is now in that class. As far as I know you can either take it during the summer for 5 hours a day or for the entire school year for 3 hours a day. Does anyone know if he can take it for the summer AND for the school year? If he can only do one or the other I need to make sure he only takes it for the school year. The reason being the before and after care is cheaper and his little brother is starting daycare in August so I'm trying to get my day care costs down to a minimum. Anyone that knows about this, your input is appreciated.
