Keep The Lights On
Nowadays, most hotels will hand you a key card that you can then insert into a slot by the door. Not only will it open the door, you also have to leave it there to keep the electricity on. Instead of turning the power on and off every time you need to leave, simply ask for an extra card upon check in. If you forgot to do this, it is not the end of the world! You can actually use any card that fits.
Always Ask The Front Desk
Great hotels often come with more free amenities than just soap. If you do not find them in the room, you can normally approach the front desk to ask for whatever toiletries you need. They generally offer basic appliances such as hair straighteners and dryers as well! There are even ones that come with gaming consoles for children and older adults who are kids-at-heart.
