Omni Hotels is using scent machines to send a bouquet of lemongrass and green tea wafting through its lobbies, a whiff of mochaccino or sugar cookie in its coffee shops, and coconut sunscreen smells near the pools. Langham Hotels spritzes rooms with a ginger fragrance. The scents are designed to evoke specific emotions from guests. Westin hopes a whiff of white tea will help calm guests down and diffuse stress from their trips. Sheraton‘s fragrance [fig, clove, and jasmine] is supposed to make guests feel is if they belong. And soon, Starwood’s Four Points brand will use the tang of cinnamon to help guests feel comfortable. The company is also considering changing the scents to reflect each season.

Smell is of course a powerful memory trigger, and a pleasant smell sure beats the odor of cleaning fluids, smoke, or the chlorine from the pool. I just hope they don’t overdo it.

Introducing a smell is a greater risk than upgrading the beds. Cloves or white tea aren’t everyone’s cup of tea taste preference, and you risk alienating the guest with a scent that’s too overpowering.

What’s next? Will there be scented and unscented rooms?
