I guess it started even pre-stay. They had upgraded me to the park view room, and I chatted in the app that I was interested in a complimentary or paid upgrade to a suite. They wrote back to say they made note of my Ambassador Elite status (for those who don't know, the levels in the Marriott loyalty program are member, silver, gold, platinum, titanium, and Ambassador which requires 100 nights and over $20k in spending per year) and would do their best to upgrade me on arrival. All room categories including suites were still showing availability, but at arrival the rather snippy front desk clerk said they only do one category upgrades no matter what level someone is and the only way to get a suite is to pay full price for one. Ohhhh kay.
The TV screen that is supposed to have your name on it had someone else's name; fearing one of those "someone else gets a key to your room" situations I again chatted in the app and they told me not to worry about it because the TVs sometimes take awhile to update (which it never did during the course of the stay). This also led to me to think there might be problems with room charges or points earning, but that didn't turn out to be the case.
We had a nice dinner at Fleming's and charged it to the room, but didn't earn Marriott points for it because it is considered an outside vendor (this would have been nice to know in advance).
The second night the HVAC wasn't working in our room--no matter what I set it to, the fan simply wouldn't come on. So I chatted in the app again and they assured me engineering would reset the unit remotely. We settled into bed but 30 minutes later there was a knock at the door--engineering actually had to come into the room to diagnose the problem, THEN 30 more minutes later they did in fact reset it remotely. But even at the "max fan" setting, which I was hoping would generate some white noise to help mask all the other sounds, it was pretty anemic.
So we packed up close to midnight and just drove home. We weren't going to get much sleep anyway, which is the most basic function of a hotel--to provide a safe and comfortable place to sleep. And we know not to stay at the Westin again.
