Not to mention to OP made sure they had plenty of places to escape one another, not like they were crammed together.
If the OP didn't have the option of a second tank available - say you only have one BP and the power is out - an alternative is to put the snake into a tub with a lockable lid and ventilation holes on the sides, and put it in the bed with you. It wouldn't be ideal, but it should survive the night.
