traveling 20 hours with snake and have questions

[redline23]

Hi guys just want to make sure i am doing things right before i go on this trip. I am moving up north and I have bought a travel tank for my snake..the biggest one they had but still pretty small honestly. i have it packed with paper towels on the bottom so its soft for him. I will be stopping at a hotel for one night and I am wondering should i take his tank in the hotel and switch him out of the travel tank and into his big tank for the night or will he get all confused and freaked out if i have in in the small one then the big one then back in the small one the next day for the second half of the drive. Any other suggestions on how to ensure he is comfortable the whole time. I really don't want to stress him out anymore than he naturally will be with the traveling. should i cover his tank with something so its a little darker? I just feel concerned about lack of air through the top then. Sorry for all these questions It's just a huge trip and I don't want to upset him. Please let me know anything you guys would suggest or do differently please. Thanks guys!
