What about you? Are you driving there? Snakes travel VERY well by car...I've traveled farther than you're going (across 5 states the last time I moved) & had a dog,
some rodents and 15 snakes with me. I stayed in hotels that allowed dogs & paid the surcharge for dog (and they really appreciate seeing that you have a crate for
your dog, btw) but never "mentioned" my other (ahem) "companions". Small cages are easy to hide in a box or with a towel over, and all snakes should travel ONLY
in "ice chests" (or styrofoam boxes), which to any normal person just looks like your snacks for the road trip...it's never questioned when you bring your stuff in from
your car. You want to securely bag each snake (how many do you have?) & not crowd them, use multiple ice chests if needed; a towel under their bags for absorption
in case & also padding. I took out my snakes each night to give a drink of water, they were all mellow as could be, not stressed. Very easy traveling with snakes. Be
sure you don't feed them prior to the trip...let them be "empty" for 10 days prior. And for altitude & seasonal temperature changes, take some heat packs for portable
warmth enroute. You should also use one of those folding foil-lined windshield reflectors to cover the ice chest(s) to keep the sun that's coming thru the car windows from over-heating the ice chests while on the road. You want your mind on the road, not the back seat.
