If you book a hotel through the Marriott app but don’t show up, your credit card will be charged. According to a query on Lulin.com, we learned that the Marriott app for booking wine indicates that you have already booked and paid for the hotel. The deposit will not be refunded whether you check in or not, so your credit card will be deducted even if you don't check in. The Marriott Bonvoy app is an application owned by Marriott Hotels. It is customized for the majority of member users. Through it, you can check all Marriott hotel information at any time. It is faster and more convenient to select a hotel online, and make reservations and check-outs easily.
