Yeah... its why he doesn't want anyone to make the computer angry, I think. For Roxas, Marina is going to be home.
[And Sora really wants Roxas to be able to have a place to call home... everyone should have that, regardless of who they are. It doesn't matter that Nobodies don't have hearts... they're still alive. They can still remember stuff... Axel remembers his childhood when he had a heart, and Namine is so creative... how can you not consider them people?]
Its not!? Uhhh, uhhh.... maybe our room? Riku and I share a room in the shelter.
[Riku probably wanted to keep an eye on it while Sora was absent.]
