No it won't go bad in that short of time. WHen I travel out of town for a couple of days I make up a few pre loaded needed and carry them in an insulated pack and always keep it away from heat.
Best rule of thumb is if you keep it cool, even without ice pack, it will be good for 10 days.
If you are traveling, keep it in an ice chest, in a sealed plastic bag on top on other things, don't let it touch ice or sit inside icewater in chest and you are good to go.
Hope this helps
