Most of us will likely travel to overseas destinations (same location) only once for photography. If we do go a second time to the same area, we will generally shoot something else unless we really mucked up the first time.
What we fail to get is that the light for any area is changing (angle of the sun) throughout the year. Combine that with the fact that we have to account for weather variations on top of that, it's hard to imagine that the first time will be the 'one'.
I have on example here two photographs of the same place. The colour one was just taken yesterday and the BW photograph was taken a few years ago in the month of October. Usually speaking the water flow is usually more in the spring and less in the fall, however due to freaky weather, this is reversed in the examples. One more reason to re-visit the same spot.
If we only had unlimited financial resources and time to visit those exotic places several times, life would be grand.
