I sometimes see moving or directional verbs doubled up, with the first verb in
て form. I think my professor mentioned that this just sometimes happens but
means the same as if you didn't have the second verb. So essentially the
following 2 sentences are the same (both meaning `I went traveling`).

```

    旅行に行きました
    旅行に行って来ました
    
```

But is there any nuance difference between the 2?

I might also be wrong. Something tells me this might mean `I went traveling
and was still there`.

translation verbs て-form
Doubling "Moving" Verbs （行く and 来る)
The first is simply "I went on a trip". The second emphasizes the fact that
you went an on trip and are (somewhat) recently back now.
