For now on any hotel that I stay at I have to make sure that I check the pillows, the bed sheets. And yes, even the toilet paper from both sides needs to be checked. I also have to make sure that I put a do not disturb sign outside my door as tired as I may be, all of this has to be done. Trust me, no matter what five-star hotel you're in, do you want to do your own inspection before you lay your head down..
