BTDT. Good news you really probably only have 1-2 more summers of doing this.
I started doing some home time with my two when they were 11 and 9.
We also had summer school through the public schools that took care of a full month, was free, and provided transportation. This was awesome. My kids got to take fun things, and learn some valuable skills that they needed for later in school.
So check out your schools to see if they have that.
