The First thing you will do is to get your cc ready to process the hotel booking online. I will advise that you go for non-refundable rooms.
Your cc should be of high balance to cover the hotel fees.
Make an email with the cc holder name and get ready to start the process.
Visit (https://www.booking.com/) and make a new account with the cc holders detail. Now, proceed to login and browse available rooms for the country/city you want to book a hotel in.
