I'm not sure if this had been brought up already, but I just wanted to add it in case it hasn't. Two older rabbits would be a good idea if you were going to uni in a few years, but I don't think that you can insure rabbits over 5 or 6 (correct me if I'm wrong), so you would have to be prepared to pay some big vets bills if they ever get ill (especially if it's at a weekend or late at night).
I am still also concerned with the moving the bunnies around a lot if you go away several times a year. I think that the constant change will be stressful and could make them ill.
