It's not clear from the video to what extent the same germs/bacteria tendd to be present in either your own home, or that of your G/F or B/F or even your extended circle of family and friends. If all of those people live in spotless, sanitized dwellings, then clearly a night in a hotel represents a massive increase in risk - if they don't, then what is the actual risk?
There are so many things to worry about - the difficulty is in knowing which are the ones that really matter. You can use your flashlight to check behind the headboard for bedbugs: You can walk around the room in socks and not use the hotel glasses, or drink from the taps: You can hide your toothbrush, have the minibar emptied and roomsafe your lipstick.
There are crew who do all of this, and yet will accept the risk of going to a club, recommended by a stranger, in a foreign country, wearing jewellery, with somebody they haven't met, while drunk - and think nothing of it.
Everybody's level of acceptable risk is different. In attempting to reduce or eliminate risk it is perfectly possible to make life impossible: You could end up living like Howard Hughes in his latter days.
