Yes I use and put reviews and photos on TA.
Kudos to Novotel Sydney Olympic Park, I neg reviewed our room with photos and they tracked me down via room number and we were offered a free suite for an event night later that year (rack rate was $500+ that night), with welcome fruit basket no less.
Pullman Olympic Park also recently came to the party with a free dinner because of a few tiny issues we had with our last stay.
I do like when the business reps respond to reviews.
That is what is wrong with TA, write a negative comment and hopefully you get a free room or upgrade next time.
