I know it's expensive, but I recommend a proper overnight sleep study in a Sleep Disorders Center it is way more detailed than the data you can get yourself (I tried).
Well, Google can "correct" your spelling and take you to the correct city (let's say it's not a big deal), but mainly Google Maps rules for multiple points navigation A->B->C->... I think it allows 10(-ish) intermediary points.
I even used a Trail Cam to film my movements :)
