He will be fine in the tank or anything you put in as long you provide heat packs. They are very cheap and easily found in walmart.
I transported my snake in the tank when I moved from NC to Utah. I put my heat pack in a sock, tie it off and put in the hide. I also removed water bowl so it won't slosh around and splash into aspen bedding. I never had any problem at all.
When you are staying in the hotel, make sure you bring the snake in with you all the time, try to be discreet about it because some hotels do not like that.
Good luck![]()
