Hotel no-nos —
Anthony Melchiorri, hospitality industry veteran and host of TV series "Hotel Impossible," tells CNN about the worst mistakes hoteliers can make. Here are the biggest no-nos.

Hair in the drain (or anywhere) —
"When you walk into a hotel, the first thing we have to do is, we have to make believe that the room has just been built -- for you," Melchiorri says. A hair in the shower? A stain on the sheets? Poof: The fantasy is gone.

Inattentive front desk staff —
Consider the front desk staff your parents, Melchiorri says. If anyone makes a mistake, it's the front desk's job "to be the person that makes everything OK, gives you a Band-Aid, gives you a lollypop." Bad things happen when the front desk "parents" don't give their kids enough attention.

Micro or invisible managers —
Hospitality is about people working together to create a great experience. Micro-managers may deliver a great guest experience, but they don't trust their own staff, so they'll probably run through personnel quickly.

Missing amenities —
There's no sin in having a pool. But in some cases, it's a sin not to. Going pool-less doesn't have to be a business killer, but it's definitely a reason to be extra nice.

Skimpy basics —
Those bedspreads. Those emaciated towels. Things like outdated or threadbare linens are a guest turn-off.

Review blindness —
Throwing up your hands or ignoring negative reviews is a quick way to torpedo your business.
