This is not a birthday cake, so if it gets damaged it’s a big deal. It’s your wedding cake! This is one of the most important days of your life! Have it delivered!
I am a small business and part of my service is to be with that cake until it is delivered to the venue, set up on the table, and the final decorations are put on it. If it gets damaged during setup (like a fresh flower toppling down the front of the cake and messing up the frosting), I will be there and can repair it so it will be perfect for your pictures.
