I am taking my kids to US and IOA in early November. I am hoping the crowds won't be terrible during that timeframe but I want to know what others that are more familiar with the park think. I now RRandR and HP are huge draws and may significantly increase crowds during that time. What are the expert thoughts on crowds? I haven't booked yet and could do it during the Sept. time or early December if either of those times would mean lower crowds.
