Until when can I check the credit card details?

You got a reservation, but until when can you retrieve the credit card details? This article tells you how much time you have to check the details.

You can check the credit card details anytime between the book date right up until midnight on the day of departure (UTC). During this time span, you can check the credit card details only once, for 120 seconds.
If you don't retrieve the credit card details, they will automatically be deleted following the departure date.

SmartHOTEL cannot help you with recovering the credit card details. When they're deleted, they are gone for good.
