Why such skepticism???
IMHO, Colony Square (with the addition of the high-end movie theater and restuarants) will generate a lot of foot traffic and become another destination for residents and visitors to the city. People love to be the first to visit new and shiny venues, and this will be no different.
I used to work at the 1180 building across from CS, and now when I visit 14th and Peachtree streets are busy with people walking from West Peachtree to Peachtree for lunch and throughout the day.
Also, the nightlife on Cresent and Juniper streets creates a node that can only get better with the renovation of CS. Atlanta is getting that urban vibe and Midtown is leading the way. When the dual hotel opens up, there will be move millennials walking about the district.
Let's be patient and think positive about our rapidly changing urban environment.
