We camp for the summer at the KOA every year and we really like it alot.  It changed managers again, but I am told they are supose to be good (time will tell). I love the amenities the park has.  It is pet friendly, has it's own laundry facility, arcade, swimming pool, launchramp, store and fuel.  The hookups are all full hookups (water/power/sewer) and most sites have a nice patio and picnic table.  The cabanas need to be rented pretty far ahead and are around $125 a month.  The old managers use to give a discount if you were refered by a monthly rental person (10% I think) but not sure if this is still true.  You can rake your golfcart or SXS to cruise around the park in, but they were frowning on quads and go carts (obnoxious family running into stuff ruined that). There is a basketball court for the kids to play on and a lagoon you can park in for the night, but be careful when the water drops that you don't moor your boat up too high on shore or it'll sit there half the day wiating to get back out 

Enjoy your summer everyone and stop by to say hi anytime you're in the park. We are on the end of the island on the right side of the park.
