2 tanks 1 axolotl ?

I have been considering getting an axolotl since I will be in college soon ( a week ). My college only allows fish tanks in dorms. Before I get one I'm going to talk to my roommate and the housing department. First, to see if there are any tank size restrictions, as I wouldn't want the Axie to feel squished. Second, to see if my roommate is ok with a fish tank in the room. Considering that were both Bio majors I'm hoping it won't be a big deal.
I was wondering what some of you experienced Axolotl owners think of me having 2 tanks for 1 Axie. I was thinking about having one tank at school and one at home for when I come home for breaks, since I don't want to be taking everything with me back and fourth. I was planning on having both the tanks have similar setups, although the one at home would be bigger due to more space, but would it be to stressful for the axie? just wondering what you think of the idea. I'm not planning on doing it right away so no big rush. Still got to get myself settled in and get the aquarium. Sadly I had to get rid of my last tank. It was 3ft long and would have been perfect for home, not so sure it would have fit into my dorm room.

My dorm rooms allowed 20 gallons, which would work for 1 axolotl. Your idea will work, however the only break you're really going to need to take your axolotl home is winter break, but I do remember how much hauling a 20 gallon back and forth on breaks sucked. Just remember when you switch from one tank to the next to keep the bio media wet from your filter submerged. As long as you keep the beneficial bacteria alive, transitioning from one tank to the next won't be too hard.

Another way to do it may be to have the tank at home/ at uni populated with guppies and red cherry shrimp, both of which are quite happy at 18c (my red cherries in my big tank are currently at 12c and doing EXCELLENTLY!!), that way not needing to fuss around with moving filter media (not to mention your axie will have a nice snack if they need one!)
