While I wouldn't say the existing Citywalk is struggling, I wouldn't say it's exactly thriving either, especially compared to Disney Springs. As things stand now, dropping down a second "Citywalk-like" area in the resort would likely cannibalize the attendance of the existing one, and create unnecessary competition between the two. Even if it is many years down the line, I don't know if a project like this would actually be a viable business move.
