I have gone both early August and late August a few times. Late August was less busy than early August IMO. It is considered value season. We are tired of going in August so we are going July 4 to July 14. We are in regular season. When we went a few times in mid to late June during regular season we did not find it as bad as early August. We are willing to pay for the regular season rates in July and try something new. I did get a 30% off PIN code that I used for my July trip. It indicated that it was for July but in fact it was good for all of 2012. Happy planning!
