Oh yes, forgot about breakfast...
I don't usually have anything bar espresso and Gauloises for breakfast, but, if I've got an early start (i.e. before 7.30am - I'm not a morning person), I'll usually order breakfast, as it's the only way to guarantee I wake up.
Actually, that depends on the hotel. If I can get a decent fruit and cereal breakfast (or good poached eggs), I'll order the breakfast. If not, then chances are I'll just go for some proper coffee (i.e. not the in-room stuff).
