Honestly, IF a ST pop-up store came to I-Drive and HHN was doing a house, neither would affect the other. I literally just did the ST pop-up on Saturday here in Chicago. While it was cute and all - some nice little photo-ops, and the ST logo on pretty much everything from cereal to shirts to Pez, it was kind of a let down. The scenic and detail that were in the HHN houses was much more exciting. This was really a glorified cash grab - a lot of hype and a lot of over-priced merch. If anything, having the two close to each other would probably be more of a benefit to each.
