I stayed here as an overnight guest and attended a conference in the convention facilities. All spaces were clean, updated, and nicely decorated. Room was spacious, functional, had good coffee and amazing showers at a great rate. The conference facilities are ample, and if the catering was in-house, was above average for conference fare. The staff was friendly and helpful as I discovered at check-in and after realizing I forgot to pack a toothbrush and toothpaste. I would just offer a word of caution to other out-of-towners expecting the Denver experience: it's accessible but not that close. Car shares are still affordable-ish to Denver, but it's probably more cost-effective to get a rental. Public transportation is available nearby but will take an hour or so with transfers.
Well..not exactly what I'd expect from a Hyatt. We did get a room upgrade which was really nice but there was no club level - which is what you'd expect from a regency. Also I wasn't permitted to eat my breakfast (which was some oatmeal I bought from the store) with my friends. Also they'll charge you $15/night parking- ridiculous considering there was huge plots of empty land all around
