I accepted as I just wanted to rest (flew coach for 8 hours)... and whilst I have no regrets on my decision, it is worth sharing here that their standard rooms are by far one of the smallest I had seen in any 5* SPG.. er.. Marriott properties I had been at in Thailand. If size matters to you, more so than getting into the room early, opt to wait it out for a bigger room. Probably not as necessary in places like LM Bangkok, SGS or even the WGS where even the standard rooms are of decent size. Not here. The toilet seat was literally 2-3 meters away from the bed.

Otherwise, a decent hotel. Great time at the Octave during sunset where they sell drinks at half price. Lounge food is plentiful. Spacious lobby. Great plat perks.
I thought it lacked a bit of warmth though. The way staff treated me were very cookie-cutter (akin to WGS or 4Pts perhaps). YMMV but I found the service professional but impersonal. Not a biggie for me though, I did enjoy my 3 night stay despite the small room.
