Which is a better time to go? The week before labor day weekend or a few weeks into Sept? Heat is not a problem, but larger crowds are! Also, trying to decide between OKW and VWL. We love VWL, but the pts are a bit more (we'd need a 2 br). Never been to OKW, but have read great things. We like VWL because of its relaxing atmosphere. OKW seems to be similar (with a different theme), but also much larger. Any input?
