If I may suggest, please come on a weekday and non-holiday as we waited 2 hours in queue. Quite normal as it's peak season, so just consider that especially this is quite a distance from the 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 a proper stop-over (own expense) before heading off to ride back to the main entrance. Grab their pics at a minimal cost. A great memento for kids and adults alike.
