You mentioned booking your room/tickets so not sure if this applies but might as well let others know if they are looking to do the same. If you book as a package you can easily make payments online. For some reason, if you book a room only reservation you do not get the option to make payments online on the website. You CAN make payments however by calling in and doing it over the phone. I have no idea why it's like this. We always book room only reservations and then buy tickets through 3rd party websites since they are cheaper. We then call and use the phone system to make payments.
