It's easy. The line to get into SWL will go pass a current smoking area. All of those people waiting to get in will be gassed.
It's only a smoking area now, because it is an under-utilized walkway. The smokers WILL be moved come opening, that's prime real estate that is questionably going to be second only to Main Street for crowd demand. Much like Tron will likely displace the smoking area at MK.
