While not getting into the issue of Wonderla pricing, it is like comparing:
Fares of 2A and 3A in trains
Better experience since only 4 pax in a bay, reading lights, toilet occupancy indicator and curtains. Are these worth paying over 35% premium?
Alto 800 and BMW 320
"premium feel', more cosmetic features and of course more power
Experience is paramount and Wonderla is taking steps like not charging for vehicle parking, limited premium ticket, RFID tag, etc..
