Smart home devices like Amazon Alexa have forged partnerships with brands like Marriott, and allow for travelers to ask Alexa for extra toiletries or room service. This eliminates liaising with a front desk, guest services, or a concierge.

From major brands to small operators, hotels are heavily investing in apps that allow for check-in from a mobile device, and the replacement of a room key with a smartphone. This not only meets traveler convenience needs, it's cost saving for hotels and potential for more eventual revenues, including booking-direct.

Hotels are also adapting to the need for additional convenience, with in-room amenities like gym equipment.
