Tiles floors and timber

Ack! It's crunch time.
There are 2 rooms in my house (lounge and study) which I wanted to do in timber (blue gum, glossy) but now I'm getting enough objections to rethink this. Is it worth the trouble?

My tiler says my floor isn't 100% flat and he has to compensate with glue, on the concrete part. On the particleboard I have to get it sanded flatter. And a carpenter is coming tomorrow to fix the squeaky panels. Lucky I have a crawl/stoop space.

People love a timber floor, and they don't love cold feet. Timber-r-r-r-rrrrrr!
