I got my tripadvisor reviews update today, 6,033 people have read the reviews I've posted.
61% of the readers are from US, 12% Israel, 5% United Kingdom and 21% other countries.
I use tripadvisor extensively and the reviews have always been on point. If you read enough of them on a particular hotel, restaurant, activity, etc. themes are repeated over and over and you know yes, this place works for me, or no, not interested.
My only ask, if you use tripadvisor and benefit from all the recommendations and reviews posted by others around the world, pay it forward, spread the karma, take time to document your experiences. It really does make a difference.
