I recently did this with my corn and didn't have any huge problems... despite the fact that it's a solid ten-hour drive. I'd suggest keeping them in a small container for the trip (I put her in a sock and put the sock in a deli-cup), and just setting up their tank as soon as you get home. Roxanne managed it, didn't seem much put out by it, ate readily without any regurges, and even decided to shed half-way through the process, so I think you should be all right.
