I've never heard this called teacher convention week, only jersey week. I've done it twice, food and wine was going on, didnt find it overly crowded. lots of people from new jersey, they are a bit loud but all were friendly. weather was pleasant though it is hurricain season so that could effect the weather. I felt it was more crowded in mid august compared to 1st week of november. last time I arrived the day before halloween and stayed for 9 days, had a great time. I would do it again.
