LTI -- Luxury Travel Intelligence -- has rounded up hotels and resorts across the globe that are lavish, grand -- and costly, reports CNN.
The global members-only organization used a thorough assessment process to count down the top brands.
To choose the top 12, LTI assessed 118 different factors, with each factor having its own weighted score.
"The 118 touchpoints relate to the overall brand performance, rather than its individual properties," says Michael Crompton, Founder of LTI, in a statement.
"It's all about the brand's ability to deliver: its passion, commitment, ethos and values, as well as the quality of its management and staff."
