There can be a mess. (This case Pullman Kuala Lumpur City Centre)
I recently booked a prepay stay for a guest of mine. I wasn't aware that they didn't immediately deduct.
Upon checkout, they made the guest pay.
I was mad. They told me they had sent me a credit card authorization form the day after my booking - which they didn't.
So in other words, in future, if I REALLY want to prepay, I need to give money to the OTAs since they can manage prepayment better ?!?!
