Avoid these disgusting resorts at all costs!

Only a handful of all-inclusive resorts all around the world can truly achieve the highest level of customer service. The truth is, most of them are mismanaged and lead to guests being mistreated: the lack of safety, cleanliness and unprofessional staff are the main ingredients that can ruin everyone's vacation and if there's such thing as a zero-star rating, we'd give it to them.

Surprisingly, these so-called "resorts" are still in business (even though they should be quarantined already), therefore accumulating more bad (sometimes comedic) reviews from victims and today we will take a look at them so you won't make mistakes booking them on your next vacay.

Join us as we count down 20 all-inclusive resorts that treat their guests poorly (per Trip Advisor).

20 Chenay Beach Resort: "A No-Good Experience"

Don't stay here unless you want your time wasted and your jewelry stolen by the hotel staff. Another bad thing about this resort is the "No See Um" infestation according to a Trip Advisor reviewer. Don't fall for their "5th night is free" scam too. You wouldn't even last a minute in this awful resort.

19 Royal Decameron Montego Beach: "Worst Vacation Ever"

The poorly-trained staff of Royal Decameron is the main reason as to why tourists rate this establishment 1/5 stars on Trip Advisor. It's so bad that they will ignore you until you either walk away or scream at them. Don't even try to ask for the housekeeping service because they'll make your room dirtier.

18 Breezes Resort & Spa Bahamas: "A Bummer"

Another resort in the Caribbean that is flooded with bad reviews and urine. "It smelled like urine everywhere," a Trip Advisor reviewer wrote. Apparently, the only good things that ever came from this "super all-inclusive" resort were their fruits and wine selection. Other than that, it stinks terribly.

17 Allegro Cozumel: "Terrible"

This nasty piece of work is currently rated 3.5/5 on Trip Advisor. Apparently, the owners wanted to design a resort that would equal a rat hole in terms of quality and service. "The upper floors smell like mold and the lower levels are for smokers," a reviewer wrote. There's no other place to stay than outside. Be warned, don't book here.

16 Sand And Sandals Desaru Beach Resort And Spa: "Foolish Employees"

With the exception of the small pools and the beach, Sand and Sandals is a trainwreck and the entire junk show is made possible thanks to most of the hotel employees that are either too busy doing nothing or arguing with other guests. "The rooms were prepared halfheartedly," one reviewer stated.

15 Splash Resort, Panama City Beach, Florida: "A Nasty Place"

Rule number one when choosing resorts: if it has a generic name, chances are it's in a bad condition. According to a Trip Advisor reviewer, "there were bugs under the couch and the shower curtains were so moldy." We wonder what they'll find next.

14 BelleVue Beach Paradise: "You Will Get Robbed"

It's a well-known fact that some parts of the Caribbean coast are a little sketchy, with some regions experiencing an increase in petty theft. BelleVue actually takes it further by not giving a quack even though some of the staff know who the culprit was. "Got robbed on my first night," a reviewer wrote angrily.

13 Playa Nueva Romana, La Romana: "An Expensive Mistake"

It's all sun and smiles until you book into Playa Nueva Romana in the Dominican Republic. Just last year, three tourists passed away after they chowed down on poisoned food. A series of unfortunate events also transpired here. "It has the worst and most expensive food ever," a reviewer claimed on Trip Advisor.

12 Sandy Beach Resort: "Badly Run Down And Zero Maintenance"

What's with these weirdly-named resorts? Anyways, welcome to the Sandy Beach Resort in Langkawi, a low-budget resort where nothing ever works. Not even the appliances in the room nor the staff. "There was no lift," a Trip Advisor reviewer shared while recalling his exhausting stay on the 3rd floor.

11 Polynesian Beach & Golf Resort, Myrtle Beach: A 2-Star Rating For A 2-Star Resort

The Polynesian Beach and Golf Resort claims to be a resort but is actually worse than the worst motel you could ever think of. "Please please don't ever book here," a reviewer pleaded. Spare your life and avoid this nasty "resort."

10 Sun Club Gumbet: "Hotel From Hell"

This resort is situated near an adult bar, which means anyone can walk in here to ruin your family holiday. "Fresh bottled water was actually water from a garden hose" a flustered reviewer stated on Trip Advisor. Don't make a mistake and book here. You'd be better off with the neighboring resort: the Casa Bodrum which actually has 4 stars on the reviews.

9 Century Langkawi Beach Resort: "Haunted Property"

Initially a Sheraton-owned resort, now turned into one of the dirtiest resorts in Malaysia. "The property gives you a ruined feel," wrote a Trip Advisor review. Most of the rooms are average and the pool needs a total clean up. The property is so old that TVs only have one channel and there are cobwebs in the bathroom.

8 Laguna Beach Club Dusheti: "Dirty, Small And Bad Smell"

The number one resort in Dusheti, Georgia is ranked 3/5 stars, is called the Laguna Beach Club. While not too special, aside from the jet skis and bicycle rides, this resort is notorious for its tiny rooms and public bathrooms. "I ordered a cheeseburger but it didn't have cheese on it, but the waitress still said it was a cheeseburger," wrote a frustrated guest on Trip Advisor.

7 Griff Inn Bazaleti: "Awful And Slow Service"

This resort offers a room with a stunning view of the nearby Bazaleti Lake. Other than that, there's not much to say except that it belongs to the top 10 worst resorts in the world, according to an angry reviewer who spent days suffering here. "Lights went out multiple times in the day, rude manager, and slow service" are some of the major problems you might encounter here.

6 Gran Royale Solaris, Mexico: "Stay Away!!"

"We were promised an oceanfront room with a 150 Sq. Ft. Balcony and a jacuzzi," a reviewer stated as they recalled their grand royal nightmare. The management will make sure they painfully squeeze every cent out of your wallets, a 70 USD upgrade was paid by the family only to be met by a motel-room-looking suite with an awesome view: a concrete wall of the nearby theater.

5 Grand Riviera Princess: "Racist Bellboys"

What's worse than a racist staff? Even the bellboys are hostile towards their own citizens in this resort. Everything in this resort is actually cool besides the stupid staff. "The way they treated my husband was just devastating," an angry wife ranted on Trip Advisor. It seems like Grand Riviera staff needs a purge.

4 Ammos Resort Greece: "Sewage"

The ground floor up to the third floor smells like the sewers, "something like a blocked drain," a reviewer noted on his stay in Ammos Resort. This "resort" will guarantee nothing but a ruined European vacation. The food is flavourless as it is cold too and their pools are very moldy according to some reviews.

3 Barcelo Maya Colonial: "Inedible Cuisine"

It's a shame Puerto Aventuras has such a flawed resort. One angry reviewer stated that there was raw sewage everywhere, particularly on the sea. Most furniture looked pretty stained and smelly. The pools however were a saving grace but the whole ocean is unswimmable and it reeks of garbage.

2 Mark And Meadows, India: "Lack Of Cleanliness And Inefficient"

This resort charges people 5-star rates for a zero-star experience. "The property is in shambles," according to Trip Advisor and the only things that save this accommodation from total ruin are the beautiful location and the courteous desk staff. The pool looks like it hasn't been maintained for decades and the hotel looks like a scene out of Elm Street.

1 Mayangsari Dungun, Malaysia: What In The Blue Hell Is This

You probably got lost on your way back to Kuala Lumpur so stopping in a hotel would be the next best choice. Mayangsari Dungun seems like a nice resort. The next thing you know, you're scrambling out with your family because you'd rather sleep on the curb out in the streets than this filthy "resort." According to Trip Advisor, "it is really, really bad and the worst resort in the world."
