Denver-based travel club Inspirato launched its Inspirato Pass, which allows customers to book unlimited stays in luxury vacation homes, as well as legacy five-star hotel brands such as Ritz Carlton, starting at $2,500 a month with no other nightly rates or fees.

Inspirato founder and Chief Executive Officer Brent Handler came up with the idea as a way to solve a common luxury travel problem - unbooked inventory, especially in the high season.

In Inspirato’s traditional model, members - currently 15,000 - pay a $20,000 entrance fee to join and then $3,600 each year, not counting the cost of a specific trip. The membership allows them access to stays at properties Inspirato handles. Rates run from $300 to $8,000 a night, depending on the property.
