It shouldn't cost anything extra to move your snake. Your set-up sounds ok, except for one concern I have. You'll want to make sure that the inner container is totally secure so that it can't slide around inside the larger one. AND, you need to make sure that the snake is secured within the smaller container so that HE can't slide around inside it. You can put him in a pillowcase (turned inside out) and then put that inside the well-padded box. Make sure the plastic box has ventilation. And you should be good to go.


He'll be quite cozy in that little space until he can be put back into his permanent home. There shouldn't be any reason to take him out while you are traveling.
