Except FP room is 22sqm, smallest room in Keraton is 60sqm. So to me the price difference is justified. I have paid 2.546jt ++ for Keraton for an Executive Room before so with the facilities, lounge, and the size of the room, makes it worth it for me to spend my money at the Keraton instead

Of course, absolute value is still 3X more than FP (1jt nett vs 3jt nett)
