If you have a TA make sure you go through them.
I had to do this as I'd originally booked under the name listed on my drivers license, but forgot that my passport has my maiden name as part of my name. Legally my passport is the right name, but the state wouldn't put that name on my driver's license but that is a different story all together. Anyway, when I realized I was going to use my passport I called my TA and she changed my name in about 5 minutes I think. Its always safer to have all parts of your name match the documentation you have.
