Stephanie Linnartz, president of Marriott International, joined Cheddar's "Closing Bell" to talk about the launch of the Marriott Design Lab, a new facility within its Bethesda, Maryland, headquarters to explore innovative tech offerings for bolstering the guest experience. "It's all around figuring out how we can innovate in the guest room in the public space, looking at how we can use robotics, improve sustainability, etcetera," she said. Some short-term changes in the future Linnartz also noted is an expansion of the chain's mobile capabilities to make check-in and check-out an easier process for guests, as well as mobile room service, from the feedback it received during the pandemic.
