"Amsterdam has banners all over advertising the Torture Museum. Spoiler alert: humans are terrible. There, I saved you fifteen euros."
Jianantonic had a similar experience; "I went to a torture museum in Prague (there were at least two) thinking it would be really interesting. Turns out it was a huge bummer. And there was no gift shop. It was a good museum, though. Really well-done and informative. But torture is a real downer. Don't know why that didn't occur to me before going."
If you must go, maybe don't bring your kids?!
What to do instead
Mom_is_watching has a more wholesome option; "A very underrated museum in Amsterdam is the Cat museum. It only has art about cats and there are four or five real cats wandering around as well."
Roswell, New Mexico
Properrocky says, "You'd think it would be a hotspot for conventions and space geeks, but it was an incredibly tiny town with dozens of alien shops and barely any people. It was creepy as hell."
Astrdrmars, "Omg I stopped there on a road trip and wouldn't recommend it. We stayed at a motel 6 that was painted neon green. The room had what we assumed were puke stains on the walls. There was also a caravan of crackheads in the parking lot. My ex said he heard them talking about someone they had killed earlier in the night while he went to go get ice. Needless to say we locked ourselves in until morning."
What to do instead
Winterwonderland88 says "Skip Roswell and go to Carlsbad Caverns. Absolutely gorgeous.
White Sands is also breathtakingly beautiful and the sand is soooo soft and cool."
Hollywood Boulevard, Bourbon Street, Times Square
Astroidzombies says of Bourbon Street; "Just a bunch of homeless people and the place smells like straight up shit from all the sewers around
Tokomini makes a fair point, "I think most people who party in the French Quarter either don't care, are too drunk to remember anything, or understand that they're collectively the ones contributing to the stench. It's like going to a week long summer music festival and complaining about the body odor - well yeah, when was the last time you showered, Mountain Quest?"
SafetyDanceInMyPants has this to add, "As a New Yorker who works by Times Square and walks through every day, I encourage people to walk through it — as they probably will anyways on their way to a Broadway show or the like. It's something to see. But the thing is... once you've seen it, keep walking. There is nothing there you want to buy."
Prolificus1 is LA born, and would never bring anyone to Hollywood Blvd during a visit, "MAYBE, drive through it. Fast. So many cooler things to do in LA than see a crackhead Spiderman fight a crackhead Batman."
The Grand Canyon's Skywalk
TommyHole, "Total rip-off tourist trap. It takes HOURS to get there from Vegas, they charge you $20 to park in an empty deser, they charge you $30 per person to take the bus from the parking to the attraction (it's like walking from parking into a mall - no distance at all!), then they charge you $30 per person if you actually want to walk on the bridge.. You cannot take pictures or bring a camera onto the bridge, but they will sell them to you, of course. There is one overpriced place to eat where they sell you canned food heated up in a microwave for big money... or you could drive 5 hours back to Vegas... Go there to get scalped."
The Mona Lisa, and other assorted masterworks
While the Louvre is wonderful, many argue the Mona Lisa was a huge disappointment. The painting itself is tiny and there are always hordes of people around it. There are a million better things to see at the Louvre.
Yoinkie2013 says, "The wedding at Cana right opposite of Mona Lisa is 1000x better. Plus while all the tourists are busy trying to take a pic of Mona Lisa, you can enjoy all of its glory in a bit of peace."
DJ_DD added another masterwork to the list of average experiences, "Little mermaid in Copenhagen. 90 minute walk for a 12 inch statue."
But Themediator clapped back, "Well mate, it is the little mermaid."
