Helios is a great place to start  nude camping, not anymore expensive than most full service camps. the 3 stay and be a member rule is a bit much but not carved in stone.    $500 for full family membership and $500 a year for your own year round campsite is a steal!  that's $1000 a year total, most campgrounds are way over $2000 and you have to wear clothes!  As for LS, it is there but kept indoors.   Try it for a weekend
