I was wondering too! I don't know if spending coins to upgrade characters will take away from the total that's been adding up to receive the rewards! I can't play all the time, so I only check my town twice a day max, and coins take a while to accumulate. I don't want to spend it all on upgrades, and have to re-collect to win the prizes! But at the same time, I'm stuck on 3 different tasks that require upgrading Bart and Lisa so I don't know what to do anymore. What do you guys think??
there is 0 benefit.
at the end of event, its just bragging rights. others will be able to see what level you got up to, thats it. just pixels.
