How long will coral live in the bag?

[Animal-Chin]

So I'm traveling and thinking of grabbing a couple of coral Thrusday evening but wont be home until Friday evening. Will LPS coral live in a bag for 24 hours where temps would fall to 20ish degrees? I'd just be putting them in my suitcase.

I assume it takes at least 24 hours from the wholesaler to get them to the stores but do they ship with heat packs or anything?

Thoughts?
