I'm really struggling to work out what you're trying to say there.
You are quite correct that other factors will sometimes influence a customer's experience, but that can be for the good, as well as the bad.
The reaction to being placed in a hotel room unlike that suggested in the brochure might depend on, say, how good or bad the journey getting there was, assuming of course that the view is there somewhere.
Are you asking TA to ask reviewers and forum contributors to be a bit more objective?
Or are you asking TA not to delete comments that confront lack of objectivity?
If that second question, then deletion of posts has more to do with how the difference in opinion was delivered.
For example, if I had simply responded to you concerns with a simple: "move on man" you probably wouldn't have appreciated and besides, "move on man" wouldn't be in the least bit helpful, would it?
If, on the other hand, I responded with a simple "so what", or "who cares?", then, apart from being just as unhelpful I would, in effect, be trying to manage the content of the forum, applying a form of bullying.
If I were a business owner who responds to a question or concern with a "who cares" it would not reflect well on my business and so TA would be doing me a favour by deleting such a post.
I see from time to time that people appreciate businesses that take criticism on board and make changes, so, if I were a business owner who responded to a question with a "who cares" and then, rather than learning from the deletion of my post, came back in here trying to have a go at TA about it, then I would be showing myself up as being the kind of business owner who doesn't evolve. And that too would not reflect well on my business.
So do you now still think TA should adjust the guidelines ?
As for your comment on editing reviews: that too is difficult to understand.
You seem to be saying 2 separate things and putting them together.
You imply that all reviewers asking about how to edit are wanting to do so with malicious intent.
That is simply not true. Many reviewers simply want to share information, such as whether the shower head is adjustable, if there's a lift, how far to the beach... these are all straight forward bits of factual information that they might want to pass on. Then later they realize they've left out just such a tidbit and want to add it.
If I were a business owner demonstrating one sided, blindly negative presumptions of reviewers motives over such a question, that too wouldn't be a good advertisement for my business. Just saying.
And then, you imply that these pent-up fuses, ready to smash a business reputation are going to go all sweet and friendly and say something nice about the business instead, simply because their question on how to edit was politely answered. I can't even begin to work out how you arrived at that conclusion.
If you're suggesting such questions should not be answered then that would resolve nothing.
Or, are you simply saying that people should not be able to edit reviews to which management have already responded to?
