Although the accommodations were nice, the service and amenities weren't up to the standard you'd expect at a JW Marriott. Specifically -- when we reserved our room we indicated 4 guests, but on arrival were assigned a room with 1 king bed. The first staffer we spoke with was very unaccommodating. After speaking with a different staffer, we were able to change to a room with a king bed + sofa pull out. Unfortunately we found that room had no linens and it took 3 calls to the front desk to have them delivered. Lastly, the air in our room didn't work well and it stayed warm throughout our visit. I did, however, find the valet staff and the Nox grille staff to be very attentive. The breakfast buffet at Nox was delicious. This hotel has the makings of a wonderful luxury hotel, but needs a bit more attention to some of these finer details.
