My first thought was this meant that they were going to be keeping Tatooine Traders for a long time if they are refurbing it, but seeing it's only a month refurb, I think that's reading too far into it. They're probably just upgrading some of the inside to provide an outlet for all of the fans who cannot get into Galaxy's Edge when it hits capacity.
While Star Tours story would make sense right outside Galaxy's Edge, especially if it were to exit into the land, Tatooine Traders could also be made to fit as being a store on a different outpost. However, then we're looking at a mini Star Wars land in the park where there is the actual land? And that is also a big story line for another area of the park that really has no other stories or immersive elements to it. I see them keeping it all while the initial demand for Galaxy's Edge causes it to hit capacity, but then to be re-done. Otherwise it's just an identity nightmare.
