Well for the C&P or use points question you can check the http://www.flyertalk.com/forum/starw...sh-vs-c-p.html thread and the http://www.flyertalk.com/forum/starw...sh-points.html thread.

For the Gritti, did you check out the http://www.flyertalk.com/forum/starw...er-thread.html thread? I do believe there are some reports on room size and even a picture or two in there that might be helpful.
