Everyone has differing views but all I can say is that The Fairmont Dallas was excellent. The staff was very friendly, called us by name and the Gold floor room was very nice with a great north view. (for $39 extra/night I selected the upgrade to this floor which gives you better bed quality, a huge breakfast(6-10am) and hors d'oeuvres 5-7pm.) I understand that some can have bad experiences from time to time but my approach is, be friendly and social and you'll get the same back in return.
Phillip the concierge, Tony the lobby host and Donna on the 18th concierge floor were all remarkable; loved them!
The Fairmont Dallas was perfectly located in the heart of downtown, just blocks from the DART and free trolley.
I fully recommend this hotel to travellers.
