Last year, I went opening week 3 times. Each day I went was really busy, but that was only in the afternoon with all the schools that didn't get out yet going on their end of the year field trip. However, it started emptying by around 4:00 or so, and was pretty empty after that.
I went opening day last year and the week after that. I Thought opening day wasnt too bad, just bad lines in the afternoon for the newer coasters. And the next week was alot like how twixmix described it, busy in the afternoon but emptied fast

It's impossible to predict if it is going to be busy on opening day, especially this far away. It could be rainy and 40 degrees out on opening day with very light crowds or it could be sunny and 80 with heavy crowds.
