nquinn,
I know this is late for you since you just went on the trip, but for others this might help. The Instructor VIP trip (IVIP) is basically this:
Wednesday- fly into Charleston in the afternoon, tour downtown/hang out that evening
Thursday- 0900-1200 tour power school, sit in on a math or physics class, meet with director of school, learn about train-up period and officer development school.
1200-1300 lunch with current instructors, informal Q&A
1300-1500 discuss Naval Reactors interviews and go over commonly asked questions.
1500+ dinner/hang out downtown
Friday- fly back home.
Hope this info helps.
