In a survey conducted by the Luxury Institute, high-income travelers were asked to rate their favorite luxury hotel brand based on factors like quality, exclusivity, social status and overall guest experience.

“The luxury hotel industry is growing in potential, but also in the dramatic number of brands that have top tier offerings,” said Luxury Institute CEO Milton Pedraza in a statement.

“The winners are those who can consistently provide remarkable guest experiences, as rated by the clients.”
