Haha... I take the plastic valet laundry bags. Super helpful, and they double as small trashbags on those few days I am at "home" (that far away place I'm playing rent on).

I don't take any of the toiletries. in fact, I hate most hotel's toiletries so much that bring my own travel-sized shampoo and soap.

I do wish hotels had toothpaste in the bathrooms.
