I have driven cross country many times. This should be a very exciting trip for you being your first. I remember how excited I was first time I drove from GA to CA, then when I drove from CA to PA it got a little less exciting and then.. well you get the point.
I have a few suggestions that echo some of the above responses.
Take a friend!! that is a long drive and can be quite boring at times no matter how exciting it may be. Many reasons for this, Safety of course, you are a young girl. Traveling alone cross country for first time isn't the best idea. BUT if you do decide to go it alone, make sure you take plenty of time to actually make the trip with stops to rest included. Hotel money, and all that stuff.
See stuff on the way, make a list of things you would like to see, you will more than likely not do many trips like this in your life, its an event, make it one. Landmarks, oddities, special places to eat, ect. do your research and make this memorable.
I hope you get to make the event, sounds like this would be a once in a lifetime moment for you. Just be ready to get those tickets second they go on sale as you know these events sell out quite quickly.
Keep us updated.
