Legacy hotel brands like Renaissance Hotels are adopting the same design strategies as their lifestyle brand counterparts to spark guest interaction among creative professionals.
Expedia and Booking.com are wildly successful because they're great at converting travel shoppers into buyers. In order to keep growing, however, they'll need to move further up the "purchase funnel" to capture travelers who are still in the research phase. New search features may be the way to do it.
Big hotel chains like Marriott and Hilton, with their ample marketing and advertising budgets, can scoff all they want about Expedia and Booking.com pay-to play programs for sort-order preference as the chains push direct bookings on their own sites. But small chains and independents will likely use the programs, seeking any small advantage they can wrangle.
