I too am currently playing Luigi's Manson 2 and Animal Crossing
My code is 2964-8603-0238 and I usually leave my 3DS turned on during the day with my gate open so feel free to visit (my daughter likes to come over when she gets home from school so I just leave it on all the time).
Don't chop down all my friggin' trees and dig up my fossils though! That makes me super angry!
My Dream Suite address is 6400-2559-1464 although I'm not entirely sure how the dream suite works. Can someone post their code here so I can visit and find out?
