Yep, no big deal. As others have said, just keep them from getting cold and they'll do fine. I have brought snakes along with me many times over the past decade or so with no ill effects. You can bag them, or you can put them in a "carrier" cage which consists of a miniature enclosure with either fresh bedding or some of their own from their regular enclosure.

Stress is the biggest concern with the latter option, but I generally only bring along my more tolerant snakes, so I have never had any real issues with either method (knock on wood).
