i have my first wedding cake this weekend. Suppose to be real simple. Plain white cake with white buttercream, 3 tiers.  With white buttercream roses on it.  But now it is suppose to be 90 and humid!!!!  Yikes!  Any advice for sticking these roses to this cake (sides and top) without them melting off?    Figured I would just freeze the roses then glue them on with either royal icing or buttercream?  Thoughts? 

Thank you in advance, I am feeling nervous.

Is the cake outside?

It is inside. I have to drive 30 min there.

Just apply the roses with a little buttercream for glue.  Make sure that the vehicle that you are using allows for a level surface for the cake to make the trip and turn on the air conditioning.  Shouldn't be a problem if your car isn't blazing hot when you load the cake.

ADefinitely thoroughly cool your car before loading the cake. And take extra roses. And bc for repairs, just in case.

Thanks! Planning to refrigerate the cake overnight before travel and then cranking the AC. Just wasn't sure if it would hold! I guess I am just nervous of the unknown.  Appreciate the help so much. LOVE this site for reasons like this.
