I did a Precom at NN, so I am moderately qualified to answer this.
Overall, I enjoyed the area. However, there are some things you need to know.
First of all, the area surrounding the shipyard is rough. You won't want to live near there. I lived in Williamsburg, and recommend it to anyone. Nice little college town, great atmosphere, tons of restaurants, several quality bars, etc. 30 minutes to the shipyard. York County isn't bad. Parts of Hampton and upper Newport News are ok. Just remember, the farther north you live, the nicer stuff will be. However, you will be farther from work...it's a trade off-
I wouldn't recommend the Southside (Norfolk/VA Beach). The tunnels can be a real headache.
As for what to expect? Intense overhauling. Massive tagouts. Lots of civilians and NRRO hanging around. In addition to the refuel, there will be many system alts done. In a word, the plants will be a wreck. Expect shift work at times. Long hours somedays. Extra shutdown and fire watches. The ship will basically become uninhabitable (no services). The testing following the refueling will be especially intense. Qualifying will be interesting. Everyone will lose proficiency in their steaming quals, and won't regain proficiecy until testing time. As for going home early everyday...I wouldn't count on it. I am not saying that there won't be down days, I am sure there will be. But certifying a new plant is no picnic. The first part of the overhaul may be light, but after the fuel goes in, the fun begins.
On the other hand, you will (eventually) get to go home at night, and your schedule is pretty much set for about 3-4 years. No deployments, etc. No matter what happens in the world, you will know your ship is stuck in port.
As for liking carrier life....you won't get to really experience it until the refuel is done.
I hope to make it back to that area next summer (2006) to Precom the next carrier.
Take it easy.
