Thoughts on Different CRNA programs: UPenn Vs. Georgetown Vs. VCU

I'm hope somone can share their opinions and insight into some questions I have regarding different programs. I have recently been accepted into UPenn's CRNA program for 2010. I also am going to interview at Georgetown and VCU. My question is how important are the rankings of programs? How are programs ranked? How do these schools stack up against each other? Does anyone have any first hand experience regarding these schools. I am perfectly happy going to UPenn but if I were to get into both Georgetown and VCU I need further info to make a decision. I know VCU is # 1 but when push comes to shove is it that much better of a program than UPenn (ranked 26). Thanks for your response!
