Starting next month, workers at the Coralville Marriott Hotel will begin upgrading the locks on all the hotel’s 286 guest rooms.“You can have a mobile key issued, and in essence you can check in without having to stop at the front desk,” said Bryan Stolz, general manager of the hotel and conference center.The “mobile key” links to a smartphone app the hotel has used for about a year to connect with guests before arrival.“If you book a reservation and you have that app, it’s going to text you and ask you what needs you have, what time you intend to check in,” Stolz said.Tech-enabled conveniences are helping Corridor hotels meet the expectations of travelers who have new options for their stay — think Airbnb — and for booking rooms — on platforms such as Expedia.
