How will the concerts effect crowd levels?

[luvallprincesses]

Just read that there is going to be a free Flo Rida concert in the park one of our 2 days. We are not at all interested in attending this and not thrilled about our "luck". How much impact will this concert have on crowd levels that day? Enough to plan to stay away from the park it is at (is that at US?) and go to the other park? Or at least hop over later in the day?
