The rise of the sharing economy shouldn’t faze traditional hotel chains, especially when it comes to millennials, according one expert. A new report from PwC said millennial leisure travelers belonged to an average of2.3 hotel loyalty programs, compared to 3.2 for non-millennials. When asked if this meant millennials were instead embracing the sharing economy vis-a-vis Airbnb, PwC Advisory’s hospitality leader Adam Kennedy pointed to a different reason behind the data. ‘Part of this trend might be that [millennials] haven’t had the opportunity to experience as much travel,’ he said, referring to the fact that millennials are young. When adding business millennial travelers into the mix, they belonged to an average of three loyalty programs, compared to 3.6 for those over age 30 – a much smaller spread.
