8. Vdara Hotel & Spa

Location: Las Vegas, NV

Year of Fail: 2009

Featuring a unique, curved design, the Vdara Hotel & Spa was opened in 2009. After guests complained of being singed while sitting at the pool, the engineers realized that the building’s design collected the sun’s rays and radiated them to the swimming area. In addition to skin burns, guests reported plastic bags melting before their eyes and pieces of hair burning right off their heads.
