Road Warriors! Your must-have travel item(s) for business trips?

I sleep much much better in hotels now that I have a (free) white noise app on my phone. There are a ton to choose from, on Android at least.

I realize that doesn’t help with a gift idea (and in fact kind of eliminates one), but it is my best business trip advice.

No argument from me (I have one in my purse… which I would probably have to locate using my phone, LOL).

We actually got to try out the nightlight trick this past weekend - our first travel since I bought the thing.

And the hotel had the vanity / sink in the room, with the toilet / shower in a room by itself, with no plugs :p.

For an alternative to the excellent but pricey Bose and Sony noise cancellers, I would like to recommend the TaoTronics line. I picked up a pair of in-ear buds on sale and was pleasantly surprised at how well they worked and how good they sounded. They may not be as good as Bose, but worked well enough, and at a significant price delta, to be in my travel kit.
No link because the ones I have are no longer made, but search the company name on Amazon.
