re: refrigerating fondant covered cakes?

I am not sure if this is the place for my post, so if it isn’t i apologize; however, I really need some help with this situation. I have a 2 tier cake to do this week and the customer wants dark pink buttercream with dark, medium, and light gray fondant chevrons on the first tier and white buttercream with a dark pink fondant band and monogram disk on the top tier. She will be making a 3 hour trip to the venue for her party. I am afraid that the fondant will bleed onto the buttercream. I would appreciate any advice or experience you have had with this type situation.
