I've tried stitching images together from interiors, could just be my (elementary) skillset when it comes to stitching, but it didn't turn out very well and took a lot of effort.
One bit of advice that I got from a similar post I made a while back was to shoot stopped way down, like f22, and just run a long exposure. Keeps everything in the whole place in focus. You will see some weird light leaking through windows / doors though sometimes when you have such low shutter speeds, but I've been able to adapt to it. Also, minor things like cords here and there that you missed before can be cloned out later, but I wouldn't make a habit of it, you'll find yourself spending more time cloning out bits of paper, cords, odd shadows and such than you do shooting.
I think that 11-16 on a D7000 would be plenty wide for a hotel room. When stopped down this far, sharpness and vignetting won't be an issue regardless of which lens you are shooting with.
