'If I weren't an enthusiast I would expect it to cost more on the opening day of a ride' is what I should've said. I think it's natural to assume that on the opening day of a big new thing they'd charge more. I know they don't usually and I agree it's greedy and wrong, however I think it's just a natural assumption.Why would you expect it from almost any park when it seems that no other park has ever done this?
In 2018 I went to Toverland on the day they opened 2 new themed areas and a B&M coaster. It cost the same to get in as it would any other day.
