I do quite like TA and will submit a review on around 50% of my stays at hotels if I feel I can write something worth typing. If I'm going to a hotel just to crash, get up and leave it's a waste of time and bandwidth!
The ability to look up another member's review is useful, however I'm worried my mother-in-law will be able to read my scathing review of hotel stay she chose, booked and paid for on a trip away with them
