So cake... What the heck should we do??

I love the idea of a small cake for my FH and I to cut then having a dessert bar and cupcakes for the guests. Is that rude? I'm being told guests love being apart of the wedding cake. What are you all doing? Whats the most cost efficient? We only have 80 guests. Any suggestions? via /r/weddingplanning http://ift.tt/2vWtm7O
