I'm not quite sure how I managed it, but since my husband is a Dept. of Defense employee, I inquired through Shades of Green and was able to get a rate of $182 - tax included - for our 17-24 August stay at the Beach Club. The YC - our favorite - was not available, so we have decided to try the BC.
We were also there last September - just after the 9/11 attacks and had a rate of $187 - tax included per night, but we had booked that rate long before the attendance fell off. Great time to visit though - no crowds. We rode many rides over and over again and never had to get off. I'm sure August won't be nearly that nice.
