I had to travel 2 1/2 hours with this cake, and the bride wanted a smooth buttercream, not fondant. So....I made the cakes and crumb coated them. Then, travelled to the town, rented a hotel room with a kitchenette and decorated the cake in the hotel room. The biggest concern I had was being sure I had all my tools with me, including pans in case I had a disaster and had to find somewhere to "re-bake"! It all went fine and the bride loved it.
