There is a configuration of premier room (not premier suite) with a separate small "living room". Comes with bathtub as well. Quite nice actually.
Premier suites are those at the end of the hallway with a much larger living/office room, separate from the bedroom.
I stayed before twice at Genting Grand's Grand Premier room, bad experience, both times, the fridge at room temperature (aka not cold).
Room size not as big as Resort Hotel's Deluxe room.
There is no small living room, it is just one corner with a single couch armchair.
The difference between Resort Hotel Deluxe and Grand Premier is the latter's Nescafe machine but a smaller room. Grand Premier as big as Highland's Premier room, where both had Nescafe capsule machine.
