I brought fish from Florida( 7hrs) in an ice chest with a battery powered air pump. You could put them into an ice chest and carry milk jugs of dechorinated water and do a partial
water change half way if you felt you needed to.
You could also ship them to your self. Maybe your
LFS would show you how to bag them or show you how their fish come in. Most of them will give you styrofoam boxes their fish came in.
When you get to your destination and get ready to put your fish in their new water remember to
acclimate them very carefully. The water is likely to be quite different.
