My husband and I stayed at the Fairmont after our wedding for two evenings (our "honeymoon", essentially). We had booked our suite far in advance (about 4 months ahead), notifying the hotel manager that we are spending our wedding night at their hotel and asking for certain amenities, such as a suite with a bathtub, but when we arrived they didn't have the room we requested available. Moreover, my sister had ordered a number of room service snacks and meals to be prepared in the room before our arrival. Some of the order arrived late (after we checked in) and the rest of the order arrived incorrectly.
Other small inconveniences included the TV's chromecast not working, questionable COVID19 procedures and safety assurances, and it was clear that non-hotel guests were using the pool. Finally, when checking out, they tried charge us for a number of extra (bottled water we didn't use, overcharge for an upgrade, etc).
In general, we were surprised by the lack of attention to detail and the poor service we received, considering how many times we informed them that this is our honeymoon. We expected more from such a high quality brand.
