Nice hotel, customer service short comings
Beautiful hotel well representing the JW Marriott brand. 
We stayed here for 2 nights. The check-in process was smooth, however, we felt like the front-desk person really should have informed us about the elevators -- you punch in the floor number OUTSIDE the bank of elevators and it tells you which elevator to take. We figured it out quickly after going for a scenic tour. 
We had two different reservations, 1 for each night due to the rate/pkg we booked. Unfortunately the front-desk person did not combine the two reservations (even though he pointed out that we had two reservations) and so we were locked out midday after night #1. Not a huge deal just annoying. 
One more thing that will make as sound like royal pains, the beddings were very "loud". You will know what I mean when you stay here. 
It was overall a good stay, we are just being picky. :)
