Be prepared for a TON of photographers all jostling for position to take shots. Check the weather, see what direction the wind is likely to blow in, and stake out a spot where you aren't likely to have someone jump in front of you and screw up your chances to do anything.
I went through this two years running - first year I got exceptionally lucky, the second I couldn't get squat - until we gave up and went to the mall for dinner and I caught the late launch as it was heading across the near horizon.
FWIW, you want both extremes - a wide angle (wider the better) and a telephoto for the distant shots. The two most used lenses for me that first year were my 18-55@18mm and my 70-300mm at various places up and down the range. If you have 2 cameras, pack one with your UWA, and another with a superzoom of some sort to cover as much focal ground as possible. If the crowds are like what I experienced, the less fussing with swapping lenses the better when the best shots are available (mostly because you're going to likely be in the middle of huge crowd of people).
Here is the Flickr group for the festival if you want to scope out EXIFs from other shooters besides me there...
18mm using the kit lens...
100mm (using my Sigma 70-300)
37.5 using the kit...
108mm using the Sigma...
300mm using the Sigma...
To get an idea about what I meant about other photographers (and the expected crowds in general)
And to show 'you never know WHAT to expect", these were shot with my point and shoot after we left the mall after giving up the second year.
14.3mm on the point and shoot (1/2.3 sensor, so ~5.5 crop factor or about 80mm in 35mm equivalent)
Not shown: The mall and the big JC PENNEY sign across the side of it just below where I cropped this.
72mm with that same crop factor (hence the blur, these were FAR off at this point - 360ish with 35mm equivalent)
