Anyone know of groups that post good days to go as well as wait times?

With the heat.. I really think you need to consider who is going and consider going later in the day through the evening. We went last weekend. Not too many ppl but too hot.

Best days are during the week and as early as you can. The earlier you go, the shorter the lines. But once the afternoon rush starts, lines will be about 30 minutes but they move quickly.
