Tips for tiling in a straight line for 16 metres

[col5555]

Hi All,
I have to tile from my entrance into my familiy/living area which is about 16 metre's long run.
Any tips to maintain a straight line.Tiles will be laid in a straight pattern.
Is is best to put down one single tile long run or do in sections and fill in as I go.??
Should I use a straight edge or go by my chalk lines.

should do lines,

i would get some lengths of cheap MDF skirting 5.4 long & screw these down to floor to work off.

Should choose an easier material for floor covering, lol. Masochism run in the family does it? I would go with what Gaza said ...

Oi, Black Cat, all my floors are tiled including the garage (but then none have straight lines :) )
