Well, I'm a graduate of it but that was a LONNNG time ago and we did it at the actual Navy Bootcamp which used to be in Orlando.
We actually did the 2 week "Reserve Bootcamp" that used to be done so it was pretty much the same as what sailors were doing and
we were right alongside them in the mess hall, etc.
In general, I'd say to make sure that you're in decent shape and to expect some "corrections" (yelling/criticism) as that is what you'll be getting.
Otherwise, nothing to really worry about,
