We had wood floors installed in the entire house last fall. Every single thing in the house (except what was in the bathrooms) had to be moved to the basement or garage. It took two weeks, although the kitchen was unusable for only one week. It was a good opportunity to declutter, and we got rid of a bunch of old furniture.
It was a pain, but worth it in the long run.
If you are doing wood floors, my only tip is make sure you move the fridge. We left ours, and the odor of the varnish and polyurethane accumulated in the fridge and all the food had to be thrown out. All the appliances smelled bad for weeks. Wish I'd known that before.
