Hi,
Recently I booked a resort (outside US) for me and my extended family (wife, parents and in-laws). The reviews on Tripadvisors looked very promising and it shows the resort ranking 5th out of around 230 resorts and hotels in the area. However, our stay was horrible, the hotel was super dirty, and the manager was rude and so many other issues was really bad there.
I came back after taking punch of pictures on blood stains all over the curtains and sheets, molded bathroom curtain...etc and posted a negative review on tripadvisor. To my surprise only one dark unclear photo was posted under my review, though I am sure I had uploaded no less than 9 clear other photos! It is impossible anyways to add more photos or edit a review after it is posted. I thought it could be some kind of a glitch in their system to not upload all my other photos, so I deleted the review and re posted again with the same pictures except this very dark one. This morning, again, I found the review was approved, but they picked the relatively darker picture and posted it as the only picture! At this point it is very clear to me that they are trying to hide the truth.

Also I have tried to reach them through the feedback form on their site to tell them to inspect the fake other reviews, but their form has a glitch (on purpose?!) and after hitting the send button, nothing happen and my message never arrived them.
I tried to find a working email from them that receive messages, but all their emails are no-reply ones.
Just wanted to spread the word out, so those of you who trust their reviews may reconsider.

In the old days, it wasn't possible to book through tripadvisor, now that it has a conflict of interest and became a travel agent, I think they want their hotel partners to always look nicer than they are in reality. I think I would consider booking.com or google maps reviews as a more reliable sources "through they still act like a travel agent" in the future.
