help- Moving!

[Starbuck]

Hi all,
so i am moving to Florida from upstate NY later this week, and i was hoping to get some opinions on the best way to move my 6 snakes.
right now they are in tub enclosures with lots of furniture, hides etc.

im planning for 4 days of travel;
day 1 i leave from my house and go to my parents house (3 hours by car)
day 2 is spent at my parents house, packing etc (no travel)
day 3 leave early am drive to NC (10 hours of travel), stay overnight at hotel
day 4 leave early am drive to FL (~8 hours of travel), arrive at new apartment, set up tubs and be happy

my question is this: i have ziploc travel containers (about the size of what you see snakes for sale at expos) and pillowcases. What do you think would be the best option? How should i offer them water (and how often?)? I currently have some aspen in the bottom of their containers, should i use paper towel instead?

The snakes will all be in 'people' area of the cars, wont be left unattended/in the sun, etc. Any advice on traveling with snakes?
maybe do expo vendors have any tips or tricks?

Bonus question: I also have an axolotl... and am completely stumped as to how to move him. right now im think cooler in the fridge/in the ice chest with my frozen mice/rats, with 50% water changes 2x daily. ither than that, completly lost....

help!
