Stokes is my go-to state park for unplugging and enjoying time with my family. We brought our son (23 months at time of visit) on his first camping trip this past September. He loved every minute of it.
Site T07 in Lake Ocquittunk is gorgeous and one of the few relatively secluded sites in the campground. You need to carry your gear down a narrow, rocky path that's a little steep near the road, but it's manageable. There's also a graded path into the site adjacent to a neighboring site, but you should check with those campers if they are ok with you cutting through to use it. (We opted not to disturb our neighbors and take the slope.)
I thought I would be able to launch my kayak from site 7 since it's waterfront, but there are a lot of huge rocks in the water that prevent you from getting out into the lake. We had to find a different launch spot. That was probably the biggest disappointment for us.
Still, I love site 7 and it's absolutely worth the privacy and the views every morning.
