I used points and stayed in a (ridiculously) large suite with my wife, celebrating a milestone.
I assign a rating of two stars to this JW compared to other "luxury resort" properties. The room was dated and tired. I shared this same feedback on the post-stay Marriott survey. The towels were wafer thin and threadbare. The toiletries were fairly cheap. The furnishings were depressing. However, the bed was comfy!
The staff was very friendly.
Ordinarily, I'm not very demanding of people. I think most folks care and try. I'm more demanding of Marriott as a company.
In this case I will criticize the people a small bit, and will say that the room service people could use better training. My order was slightly wrong, and they forgot to bring a bottle opener. Also, the room service food was second/third rate. It's not a huge deal, but it's also not better than two stars.
I am a Marriott Platinum Elite member. In the future, I'll save my points for a Ritz-Carlton because this JW reminded me more of a Courtyard property.
