We often visit HH in early October. One year (maybe 2008) the no-see-ums were so bad we couldn't even enjoy the pool in the evenings. I would take my son to the pool after dark and it was horrible. I don't usually get in the pool at night and I would stay in from my chin down. They would fly in my mouth, nose, ears. It was awful! One lady was completely covered in pool towels, except for her eyes to be able to watch her child play. That was the only trip where they were that bad, but I won't ever forget that trip!
