Hi there

Since we had several guests in the past, that didn’t pay the city tax and we couldn’t reach them after check-out, we decided, to take credit cards from these guests on check-in and put the number, cardholder and exp. date into their profile right away.

strangely enough we didn’t had any failures since then 

@Franziska G. 

thank you for your reply, we also had some similar issues with extras, i have already started asking credit card at check in too:) 

Have a nice Sunday:)

Manny
