A few more remarks from this great hotel. Valuewise easily top 3 in the Hyatt world for me, nominal price and location considered.

I may have missed it but didnt see any big Hyatt logo when looking for the hotel from distance (contrary to other hotels in KL and other Hyatts around the world?).

Nice plastic wrapped spounges/scrubs in bathroom (in shower + by huge fancy sink).

French red wine as welcome gift as well.

Bout the train it of course also makes sense if your hotel is by the train terrminal (like Meridien/Aloft/Hilton).

Suites give lounge access for non diamonds as well ( I booked 2 and one for plat member, both of us +1). They also got wine bottle (not sure about jars).
