i'm making a cake for a Christmas party covered with fondant, i live 2 hours from the location will my cake be OK on the drive there? help please!

As long as you a sturdy cake like WASC or pound cake. Also need to be properly supported between tiers and also I would drive a dowel through the middle of the whole thing. Also I would suggest to use a sturdy buttercream that uses shortening instead of butter just to be on the safe side.
