We homeschool, but live in a neighborhood full of kids that attend school. I have things available to do this summer. We practice music, read aloud, and have some things laying around for hands on science. My 9 year old reads for at least an hour a day unprompted and his kindy sister now carries a book with her constantly. We do a reading program. But nothing really is mandatory (other than music - we are doing lessons this summer).
If kids WANT to be out side, playing, and socializing at this age, I'm all for it! Now going into our 3rd year of homeschool, I've seen the kids make leaps over the summer in some areas without any effort on my part. And some of those leaps are in social or athletic skills which are important too.
I don't think you should feel guilty at all if your kids are working hard during the year and doing well. Enjoy your summer!
