I tried to check in at 9pm on a Saturday. Staff took about 15 minutes to acknowledge my presence. They did not speak English. And they said that they were fully booked. I showed them my booking through Expedia and they indicated (at this stage through a Malay speaking guest who kindly translated for us).
I did not get to see the room, but having stayed at the Hyatt in Kuantan (currently in refurbishment) this would have been a huge step down. It resembles more of a hostel to be honest.
