Despite its lowly status as a walk-through attraction, it has a stunning exterior, carved within a millimeter of reason to look like a crumbling temple. Young folk might be freaked out by the dark and the fireballs. Mature folk might disdain the vapid storyline involving a row between Poseidon and Lord Darkenon (who?). But it bemuses with an interesting (if fleeting) “water vortex” tunnel, and some of its other special effects, such as walls that seem to vanish, are diverting. It’s boisterous and pyrotechnic, but it’s also one of those throwback attractions they just don't make anymore, so catch it if you can. Strategy: For the best views, head for the front of every room, especially the third one.
