We live close to Smokey Hollow, but every year we make sure we spend 4-5 days camping. The kids are exhausted at the end of every day--they never stop moving. They'll swim, jump on the Jumping Pillow, rides the banana bikes, play all day and never complain that we ban electronics while we are there.
They're happy, and I'm happy, too. The staff is incredible--everything is very clean, and any questions or problems are addressed right away. The staff are great with kids. We were in a gazebo this year, which makes camping so much easier--we still cooked over the fire and spent almost all of our time outside, but we slept in bunks (and the loft) and had a refrigerator... The bathhouses are checked and cleaned frequently, which is huge. The store has almost anything that you might need, and Lodi is less than ten minutes away, so a trip to the grocery store is no big deal.
