My main concern with vinyl plank is that I'll have a lot of rolling chairs/storage that will get moved around. I've read that it's not a good choice if there is going to be a lot of wheeled traffic.
the other consideration is that we plan on being here 9-10 years and want to fix up the area so it could be used as a rental apartment. Right now that is not possible as it has no separate entrance and no oven/range for cooking. Carpet tiles would probably be better for that purpose than vinyl plank. It's way easier to repair if needed. The eating/cooking area will be a hard surface of some sort. What is there is still pretty nice.
I have nice carpet tiles in my new office at work and I really like it. I don't expect to make a decision until we've moved in, but I know for sure it won't be wall to wall carpet like is there now.
