For that few animals, if you can swing it it'll be way less headache to have them shipped to you. Have them held at the local hub, and you can pick them up on your lunch break.

I traveled cross-country with snakes in the winter. I used a reptile basics rack, and while I was driving the snakes were in bags in the tubs. I packed heat packs around the outside of the tubs to keep them from freezing in the back of the car. The rack loaded easily into our small suv, and took up very little space. At night when we'd stop, I'd set them up in the divided tubs and plug the rack in with a thermostat. Made sure that everyone had plenty of fresh water to drink.

If I'd had the option, it would have been way less stress for me to have them shipped to me.
