So, the MCV campus and INOVA are pretty different, as far as the nuts and bolts go. The thing is, most of the Cali people I know who were initially interested in INOVA lost interest by M2, because 1) they didn't want to move again and 2) they had friends in Richmond by then. If you have connections to NoVa, then you don't care so much about "leaving" your buddies in your class.
At MCV, M3 consists of teams of roughly 12 medical students/ rotation. It's not like you all walk around like a bunch of ducklings all the time, but there are 12 of you. You have a "group leader" who deals w/ schedules, etc. You have 4th years, interns, residents, attendings -in general, it is traditional academic medical center life.
At INOVA, M3 consists of teams of TWO students, presently. Occasionally they throw in a Georgetown or GWU student with you. Occasionally there are 4 VCU students. But basically it's 2 students and an attending, with maybe a resident, a 4th year. INOVA is primarily a community hospital, with a few residency programs. The match list out of INOVA has been very solid, so the "non-academic" aspect does not hurt you as far as that is concerned. You can still do research, INOVA has hundreds of studies ongoing. The patient populations are very different, and an important consideration. INOVA administration and MCV administration are also very different, as are their staffs.
INOVA bends over backwards to help students transition from Richmond to Falls Church, IMHO. The major downside, other than moving, is $$$ -housing costs more in NoVa. On the flipside, the hospital tries to offset that with food and parking and coffee. Oh, and the traffic sucks.
I chose to do INOVA b/c my spouse works just outside DC, but I also think it will be good for me because I think I have a personality that would allow me to hide in the crowd instead of trying an LP on a live patient for the first time, or placing a central line. With just 1 other student with me, and my attending knowing me pretty well, I don't think I'll get away with that.
The only thing that would make me suggest you need to stay at MCV would be if you really want to spend the rest of your life in academic medicine at a large center.
