Reputable hotel has bad reputation online. Why ???

Our friend Richard Sedley on his Twitter today was sending us on an article on the web of E-Consultancy about what importance brands should show about social media comments . A very interesting article that I read with great interest and inspired me to cruise on Trip Advisor and randomly check some hotels in Cyprus and Greece.
Amathus in Rhodes and Coral Beach in Pafos. Both hotels have positive and negative comments on this social media platform which I personally do not like. Now, the difference is that Rhodian Amathus followed up one negative and gave a very nice answer that makes lots of sense. Coral Beach never answers anything. This back turning gives the “excuse” to the guests to give even more negative reviews so as they influence more people. The conversation is only between the tourists and the hotel does not take any part.
Well this a fatal error. See by yourself here.
