Depends _very_ much on how you define productivity.

Is your job moderating a big forum? Then no, you can't really bost anything.

Is your job writing about various topics? If this requires documentation, with a bit preparation before hand, sure, you can be super productive.

Is your job coding? Offline manuals will get you a long way (assuming you don't depend very much on 3rd parties like APIs or package managers).

Now, if we exclude the 1st point, yes, you can, here is how:

1. Get a good pair of headphones. Not necessary with active noise cancelling, but ones that do a good isolation of environment.

2. Download all the tools you will need: manuals, documentations, libraries and whatnot. (back in the day there were lots of site downloaders like httptrack)

3. Download some sounds. Be it music, white noise or whatever suits you.

4. Start doing stuff.

Hint: if this is one-time, long trip, you could use that time to read a book to elevate your skills ;)
