Rearrange the bedside clock, TV remote, telephone & the table lamp, if there is one to my like - basically a clean area with less clutter. Plus, move those hotel info-mercials about breakfast, HBO/TV mini-guide, etc. that's usually on the night stand and/or bed along other advertisement.

While setting any needed wakeup calls and/or alarm on my own smart/mobile device(s) - turned off or even unplug the alarm clock - last thing that I need is for it to go off at 3:45 am set by the previous occupants or attempt to do a reset with the blinking/flashing 12:00 (most have a battery backup, but not always)

What else do I move in the room? For a quick in-out overnight stay, I try not to move other things around. For an extended stay - probably move the sofa chair with the ottoman & sometimes the floor lamp for reading, and, possibly the work desk & chair if movable for a different view, maybe swing the HDTV around 90 degree (45/135 degree, etc.) so that I can see it from the work desk and/or sofa/lounger as I get comfortable.

Housekeeping's extra work after I checked out is appreciated & compensated/tipped accordingly as s/he has to put them back per property rules for how things should be ...
