As much as AI is automating things, humans are still able to mess things up. After two lovely stays at other properties in Thailand where I was automatically upgraded 3 days out (and generously), my third property - in BKK, where I had booked a "studio suite" but 3 days out showed me upgraded to a 1-bedroom suite (and I even messaged them to thank them, to which they replied, "It's our pleasure!") - downgraded me once I did online check-in about 3 hours before arrival. They said nothing to me when I was checking in, and it wasn't until they left my room after escorting me there that I looked around and said to myself, "This ain't no 1-bedroom suite." At first, they said it was because I "indicated I would be arriving early" (I indicated 2:30pm...), but once a manager came to speak to me (I didn't ask for her lol), it was because a guest extended his stay. Either way, it all felt dishonest and ...... - especially when they were still selling a bigger 1-bedroom suite for the nights I am staying in the app. Well, *was* staying - I told them it all felt dishonest of them to at least not say something to me, and I told them I no longer wanted to stay there. I felt somewhat bad doing this, but it just felt shady. Moved to the Hyatt Regency using points - when I arrived and told them why I booked so last minute when they asked me ("You booked 20 minutes ago, kha!"), they upgraded me to a club room. After a month here, it seems that competition for 5-star hotel guests is getting hotter. Of course, had I just booked the SGS for these three last nights here, none of this would have happened!
