I picked up fish and corals on an afternoon before leaving Calgary midmorning the next day, and acclimating stuff around midnight that day (after a 13 hour drive). Some stuff was packed in a cardboard box, other stuff was packed in a styro box... everything survived, indeed some of the corals were open in the bags when I unpacked stuff. If the weather is decent (and things are well packed) you shouldn't have any problems.
