Like I said I am more concerned about the tile/floor level because its such a big area split into multiple rooms than the look of the cuts (I think I have that one figured out). Would you tile a small section at a time or row by row?
Good as long as you took the glaze off the old tile
If I was to do it I would do the longest section then branch my way out to the existing rooms making shore my grout lines are straight.
If your bedrooms are a different hight then that will make it that more difficult to make it look like all one floor you only need a floor saddle for the bathroom.
I can tell you there will be a big difference in how it will look if you stagger your tile rather then just doing straight rows. your also working with a large size tile so the bigger the tile less room for error I think any way.
