I find TA reviews most useful for the reporting of non-subjective, factual information. If an airport-area hotel has no free shuttle in an area where all of its competitors offer free shuttles, that's important information. Or if a city hotel has an on-property or neighboring nightclub "featuring" loud music until 03:00 every night (Andaz San Diego anyone?), that's also good to know beforehand. Same with lack of workout facilities, business center, etc for those who need those amenities.

The usefulness/reliability factor is reduced once subjectivity enters the picture. One can pluck some useful information from these parts of the reviews, but too many of the self-styled "frequest business travelers" are nothing of the sort - the significant majority of reviews reflect relative inexperience in staying in hotels with any real frequency.

I do find the TA fora useful - one example was when I had problems buying a Renfe online ticket: the TA forum on Spanish rail had the most accurate, clear;y-written explanation of the issues faced by those trying to use U.S. based credit cards on the Renfe website. ^
