I've only had to move my tank once. I had 2 good-sized Oscars in it and instead of putting them through the stress and potential issues of a move, I let my good friend adopt them. He had 50+ gallon tank with a Jack Dempsey in it and has been keeping fish for a long time. They still have a good home to this day. Sadly, the Jack Dempsey had to move to a different tank.
I put as much of my tank water as I could in big plastic buckets that I got from a local grocery store. All but one had a lid. I put the rocks and gravel in a bucket with some water. I poured as much water as I could in to the buckets and then packed everything up.
I set my tank up at the new apartment, rocks, water and all. I let it set up for a few days and got more fish....smaller ones that eat less
My only advice would be to save as much of your tank water, rocks, and gravel as possible and move at the last possible moment. An extra set of hands will help too. A coordinated move is better than a hasty one.
As far as the fish, your move isn't that far and shouldn't take too long. A bucket with aeration of some kind would be good. Watch bumps on the drive.
Hope I helped a little bit. I'm not an expert in fish moving, but I'm sure you'll get ALOT of good info on this subject.
