If you decide to bring him home, I highly recommend putting his container into an insulated lunch box for the trip. The temperature will stay more stable, it will be dark, noises will be muffled, and the sides will be padded in case he gets bumped. If you have a jar that fully closes (I use old peanut butter jars) that will be better than the cup he came in since the lid might leak, and two hours isn't anywhere near enough time for him to suffocate especially if you crack the lid every now and again.
I bring my fish home from my dorm during Winter & Summer breaks, four hours each way and none of them ever died during the trip. A lot of the time dorms will unplug every electronic, so unless you know that's not going to happen I wouldn't risk it (Your RA should know if they're anything like my school's).
Are you allowed to have a fish in your dorms? Or does he just kind of go unnoticed? I want to bring mine to college but I don't know if they are allowed.
What college do you/are planning on going to? A lot of times the school's website will have a list of items allowed in the dorms, including whether aquariums are allowed. My school allows a single 10g per room, but other unis have different restrictions
