Toothpaste, though once that runs out I'm switching to the disposable brushes with the toothpaste in them, I have them in the office and love them.

Shaving soap, though I'm out of the travel size and using a travel size can of shaving gel until I run out of soap at home and will replace both.

That's it, the soap, shampoo, etc I use whatever the hotel has. I do have a ton of single size packets of shampoo, but never have needed to use them.
