Will rich's bettercream keep in the trunk of a car for a 4 hour drive?

I am driving to have a graduation party for my son. I would like to make chocolate cupcakes with chocolate rich's bettercream.

A) can I decorate the cupcakes with a swirl and have it hold their shape in the trunk of my car

or should I

B) If I whip it up the night before and place in bowl, could put on ice in car and then swirl cupcakes just before party. Won't be able to rewip, maybe with spoon but thats it.

Not real sure I can fit all cupcakes in frig but can try. Can't remember I thought someone said, once whipped can leave Rich's better cream out at room temp. (which in my house is 80 degrees)

thanks for the help

Here are the handling instructions for Rich's Bettercreme (Ready to Use) but should be the same for the liquid (after whipping):

i buy this product for the ice cream store i manage for our ice cream cakes. i defintely would not leave this product in your trunk for 4 hours without putting it on ice. we use the ready to use rich's bettercreme and if it is frozen if we leave it out for more than a half hour it is all wet and not good to decorate with.

What about putting some dry ice around the cupcakes in the trunk. It isnât too expensive and it will keep them plenty cool while traveling.

You can get dry ice in blocks, slabs, snow, and pellets.
Be careful if you do use it, and make sure you use gloves while handling. It can cause frostbite quickly.
