I'm sorry to say this but I just logged into my main town to find a random move in plopped their house right next to Lucky where I wanted Ankha to go... So I guess you can just give her to someone else then as I won't be able to take her now D:
Just to let you know, Felicity has just moved into my cycling town!
I have a thread in the Villager Trading Plaza (Celadon & Nimbasa's Cycling Road) .. I don't do reservations, but you may wanna lurk over there just for when she pops up
