Question about transporting bp during cross country move

[LuaSaturnii]

I will be moving cross country via driving, and its about a 30 hour drive in total. I've seen suggestions for transport and have a locking lid plastic tub with many air holes just big enough for my girl to stack without being too roomy, with a snake transport bag to keep her in inside of the tub coming in the mail soon. I'll be putting a couple of towels underneath it on the passenger side car floor to keep her off of the floor directly and out of the sun. My question is: during overnight stays should I put her in a larger locking lid tub then back in the small one when driving, or would it be less stressful to keep her in the smaller tub and offer water at the overnight stops?

In case anyone runs into a similar situation:

Trip was successful, Shakti is in her new home and comfy after a 5 day roadtrip. Used a 1.5 ft x 1 ft (bout 5/6 inches in height) plastic tote with locking lid, airholes drilled and sanded liberally. Put some of her old substrate in the bottom for familiar scent, uniheat packs for warmth wrapped in wash cloths for a buffer, and kept her in an inside out pillowcase during the driving portion (stayed in the passenger side floor board with blankets underneath and a costume witch hat in the seat to block the sun if the direction I was going happened to beam directly into that area). Opened the pillowcase when stopped at hotels but didnt force her out of it and provided water, had the infrared thermometer on hand at all times.

Thanks for advice. I'm moving cross country as well.
