Just concluding a 13 night stay (checking out 5 Jan 2019). I agree with Kalboz that Bob Fabiano's departure potentially bodes poorly. However I booked and paid for an M Suite this time, and so can't comment on the biggest Platinum benefit or lack thereof (upgrades). I otherwise received high-quality service similar to my (very numerous) past stays.

For me the biggest looming issue is not the hotel's fault -- it's the construction of Em Spheres, which has now begun in earnest. The noise is already bordering on bothersome, and it's going to be a rough couple of years for rooms facing north (especially in the north tower) and most rooms facing the park, which look out onto the construction area. Unfortunately it seems that there are no M Suites facing Soi 22 or Rama 4, which could have been the only way to escape the noise without having other rooms looking into mine or having the sun beating into the room all day.

I discussed this with the lounge staff and even had them print out floor plans etc. but if anyone knows differently, please comment.
