How to become a Neonatal Nurse Practitioner.?

I am a high school junior and am doing some research on careers. I live in Florida, and the college that I am really interested in is the University of Florida (GO GATORS.!). I have narrowed down my choices, and my number one choice is a Neonatal Nurse Practitioner. I understand they need an MSN. But how does that work? Do they go to just about any college (university or community college) they want, and get just a regular bachelors degree and an RN license, then take a break and work at a hospital for 2 years, THEN go to a university that offers a Masters degree program for a Neonatal Nurse Practitioner. If that's all correct, does the Master's Degree program have to be at the same college that you got your Bachelor's? Or can it be a totally different school? For example, can I get my bachelor's degree in nursing at Polk State College, work at Lakeland Regional Medical Center as an RN, then go to the University of Florida to do the Master Degree for Neonatal Nurse Practitioner program? Or do I have to spend all of that time at the University of Florida?
