OP, we are down there the week after you with similar circumstances. "Almost" extended family (son's GF's family) asked us to go down that week since there will be there. We had originally planned to be there last week, but thought we would join them. They are off-site and we are on.
Our crowd numbers look about 1 digit higher than yours but we are planning a return trip in November with low crowds so if we can't do everything that we want to do this trip, maybe next time.......
