Hey, this lady, Dani Quesnel, who worked at a popular hotel chain for three years, tells you on Insider.com some great tips, or things to think about, for things she says you should never do when you say in a hotel...most will help you, and some will really help the hotel staff out, which can help you in the long run....she says you should never leave the deadbolt on your door unlocked, to prevent hotel personnel mistakenly opening your door at an awkward time...always check your room over before you settle in, so the hotel can catch if you have mechanical or electrical problems before you're all unpacked....don't book with a third party website, which can make it harder for the hotel staff to help you directly once you get there...don't leave without actually checking out, which helps the hotel know you've physically left, and they can start getting your room ready for the next guest, instead of having to physically checking each room...here's a bunch more things to know for your next hotel stay from insider.com:
