Outrageous: Extreme hotel pampering

Think before you drink!

“Check the seals on the things in the minibar. I once had a guest who had drunk the whiskey and then peed in the bottle, closed it, and put it back. I've also seen candy three months past the expiry date."

"Do not use the ice bucket without a liner. It may have been used as a puke receptacle."

Mouthing off

“Always use the disposable cups in the rooms. The glasses/mugs are usually just rinsed in hot water in your bathroom sink.”

Don’t touch this!

“The remotes for the TV are rarely cleaned.”

Cover up

“Use a towel or sheet on the chairs or sofa, a LOT of people sit on them naked. It's nasty but there is often a brown streak on the desk chair that no one think about.”

Surprise

“If you book a jacuzzi, be warned, the jet system is often completely clogged up with really nasty gunk.”

Avoid or check pretty much everything on the bed

“Duvets (doonas) are NOT meant to be slept on. I know many people are grossed out that they aren't always changed but again they are not meant to be used as a blanket... The right thing to do is to fold it and place it on the floor or chair.”

"Some maids do not change the sheets (mostly because they don't have enough time in each room and can be fired for taking too long per room). When you check in, check the sheets for creases from being folded and unused. If you have any doubt call housekeeping and ask for fresh sheets on the bed."

'Mattresses WILL be stained, with a lot of stuff. There's no way we could buy a new mattress every time someone bleeds on it, or spills coffee on it, or urinates on it. It wouldn't be practical. So we sponge them down and dry them with hair dryers, or flip them over when it's really bad."

Tasty… ?

“Your breakfast food is likely always been handled in an unsanitary manner during set up (typically desk clerks in lower end hotels.)”

Itchy and scratchy

"Bed bugs are more common than you may think."

HELPFUL TIPS

What not to do with your towel

“Maybe everyone knows this, but if you want fresh towels you should put the towels on the floor. If you hang them they will not be changed and you'll have to ask for new ones.”

Ask and you shall receive

“I'm a bellman and valet at a resort. i can give you free water bottles, tampons, valet parking, tours, shuttle rides, reservations, dry cleaning, hell even an upgrade to a better room if you just ASK ME. But no one ever does cos they think I’m just a doorman.

“Many things such as fans, heaters and even bathrobes might be something stored in one place in the hotel, if you need something you should ask for it, it's not always in every room.”

Beware of scams

“The front desk will NOT call you at an ungodly late hour, if our ‘computer crashes’ and ask for your credit card information. We will not give you a 50 per cent discount for your cooperation, and no, I would not be calling you if ‘there is a line at the front desk, so giving me the information over the phone will be quicker’.

“If you suspect a phone call from the front desk is not the front desk, please make a trip down. People can simply dial random extensions, get direct room lines, and make victims of you.”

Don't be afraid to complain

“Any haggling or outright complaining you do will likely get you a discount. I've realised people are more likely to complain at older properties because frankly they're more likely to get it unquestioned. Most won’t even bother to go look if it’s minor.”

Where there’s smoke…

“Hotels love charging smokers. It's really not worth even trying. A towel doesn’t help.”

Safety

"Hotels, even nice ones, attract the worst kind of people. Don’t let your kids run around at night, make sure your door is closed properly.

"Always use the deadbolt and/or door chain when in your room."
