I reserved my two-night stay two months in advance for a business meeting. When I arrived at 11:30 at night, the desk staff informed me they didn't have a room! This was despite having a confirmed reservation, emails from hotel manager welcoming me, etc. So... they gave me lousy directions to drive to another hyatt, 30 minutes away, and after a lengthy check-in there, got in my room at 1:00 am or so. Had to be back at the Reston Hyatt for my meeting at 8:00 am. Again, on my own to figure out how to get there in the pouring rain and northern Virginia rush hour traffic. It took an hour to get back to the hotel in the morning.
I ended up getting about five hours sleep total. I did get a room assigned when I arrived, and when I tried to go and take a quick nap after lunch, there were about 10 Hyatt staff in my room disassembling the bed. No nap for me!
OK, so the hotel is very very nice; rooms are great, everything clean, etc. But that makes no difference if they turn you away at midnight! If anyone from Hyatt reads this, I have two questions: 1) don't you know how many rooms you have in your hotel? 2) since you emailed me regularly just prior to my (hoped for) stay, why couldn't you email me saying you didn't have a room. The airlines have figured out this overbooking mess, why can't you?
Remember, all most of us want is a decent nights sleep.
