Hangzhou doesn't have a dream code yet, as it's still in a very messy state~ but it'll be a zen town inspired in the chinese zodiac, so eventually Chester and Kitty and Marshal will have to move out so I can have the remaining zodiac animals (I'm missing dragon, horse, monkey and goat).
Sundance does have a dream address, but I'm actually embarrassed... it's also still very raw, but if you'd like to see it, I believe I'm the only Mayor Nopa of Sundance in Nindendo's data. x)
