Guests staying at a Sextant hotel in New Orleans check in without any interaction with a human being. They’re greeted by a virtual concierge visible on a computer monitor but based thousands of miles away. And if they want to wind down from a stressful flight, a shot of Maker’s Mark bourbon from the lobby’s automated booze dispenser will cost them $5 — but if someone isn’t there in-person that day to check their IDs and present them with a special card for the machine, they’re out of luck.
