If you don't provide it for online check in then you'll have to take the time at the resort to provide the information. So if you prefer to add it and a CC later, why bother to do online check in?
It won't let me complete on-line check-in without providing a credit card. Then when we get there they ask what cc I want to use. Tell them I provided a cc during on-line check-in and they tell me they don't have that information.
This happens every time. Not sure what the heck I'm doing wrong.
