Unless you get into really big fish they will be fine for 6-12 hours at least. They are shipped for days. If you are going to be in really hot temperatures or have to leave them in a hot car, remember that the larger the amount of water, the longer it will take to heat. If it might be a problem, take a large plastic bag, put the shop bag inside the large bag in a cooler and fill the large bag with water and tie it shut. The cooler will give mechanical protection and make it dark. The large bag of water will make the temp steady and the fish are fine in the shop bag without having to deal with numerous water changes.
Most likely not any problems but I like to haul fish without wondering how they are doing. And I sure don't want a bucket sloshing around or tipping over!
