I have long been mystified by TripAdvisor's ranking systems – a restaurant with a 4.8 score from reviewers may rank far below another with a 4.7 score – but I've always been willing to believe there was some secret algorithm giving expert results that were more useful than members ratings alone.
Now I see that Bangkok's #1 attraction out of 219 in Bangkok is a role-playing game in a new shopping complex, Escape Hunt. Huh? You travel all the way to Bangkok, and the top of your must-see list is an hour-long session of playing detective in a shopping mall? How on earth did that get to be a more essential part of Bangkok than, say, the Temple of the Emerald Buddha, or Jatujak Market, or a Chaophraya River cruise? After opening last month, to boot. Either somebody's gaming the system, or the system doesn't work.
(I'm also curious that Bangkok should have only 219 attractions. That works out to one attraction per 60,000 inhabitants, at which rate Bangkok is in contention for the World's Most Boring City award.)
