In the past I've also tried using the phone to get the coordinates, and 
I tried several apps to record a GPX track. However, I often had the 
problem that an app terminated itself while I carried the phone in my 
pocket, when I accidentally touched a button on the phone to do 
something else with it, when the phone went sleep mode (otherwise it 
used much of the battery power) or whatever. So I didn't find this 
method very reliable.

I ended up with this device:

You can simply put it into your photo bag, and it records all the track 
where you are moving. I find this extremely helpful when I'm on 
holidays, just like now. ;-)

If you do this then you should make sure your camera's time is set 
correctly to the second. For example, if you visit a city and make a bus 
tour it *does* matter if you've taken a photo out of the bus a few 
seconds earlier or later, since the bus can move quite some way in a few 
seconds, even around corners.

On the other hand, if you know afterwards how many seconds your camera 
time was off, e.g. if you know exactly on a map where the picture was 
taken, you can account for the time offset when you apply the GPX track 
to your photos. DK provides quite a few nice options for this, IMO.
