Yeah I'd save the 10k as well. I do have to chime in though and say even the corner rooms are tiny. A good point was made earlier about them not being "NYC tiny" but they're still small. A big difference from a lot of the other W's I have stayed at. I generally do one night stays at the hotel and never long stays. For the one nighters, the corner rooms suffice. And definitely ask for a room with a view of the bay bridge. The ledge by the window is really nice to sit by and look out...
Save the 10k and enjoy your room!!
They're very accommodating there for SPG status holders...
