Seems to me that there is a necessity for a facility for reviewing a listing a second time( third time?).
How many of us have used a hotel/ restaurant/ other attraction more than once and been disappointed in the second visit?
This would have the benefit of letting other visitors know if a listing has consistently good/bad services, if they have improved/lowered their standards.
For example: I stayed at the same hotel several times, first few times it was OK and I wrote a review saying so, last time I was there is was absolutely awful but I was unable to write a second review.
As I understand it, currently the only way to re-review is to actually modify one's original review by writing a new one and sending it to TA.This seems to detract from the original review as it can give a false impression of a listing.
So, TA, how about a letting us add subsequent reviews? All it really needs, for the reader, is a check box to say that this is a second ( third etc..) review.
