Unfortunately Ionly have Gold with LCAH and rarely travel in Indonesia.
Interestingly, I stay at Pullman CP before and tried to use the upgrade voucher there and it was rejected.
Call the hotel about using the voucher when I made the reservation, the person told me to just bring the voucher at check in.
Yet the FD claim that I should inform them that I intend to use the voucher when I made the reservation.
Since it was a one night stay, I really not in the mood to argue further.
