If I may suggest, please come on a weekday and non-holiday as we waited 2 hrs.in queue. Quite normal as it's peak season, so just consider that especially this is quite a distance from city proper. The alpine coaster ride was worth the wait. It was amazing that it will end at some waterfalls, and there were available snacks, toilet and proper stop-over (own expense) before heading off to ride back to main entrance. Grab their pics at minimal cost. Great memento for kids and adults alike.
