I don't think the park opens until the 28th
Season Pass Sneak Preview Night is on Friday, April 27th, 2018. The park officially opens for the season on Sunday, April 29th, 2018. Saturday, April 28th is Media Day, in other words the park is closed to the general public that day. For exact operating hours, please check out the calendar on Canada's Wonderland's website.
Wasn't Media Day supposed to be today and Preview Night last night? Did things get switched because of the weather or did I read/remember wrong?
Is this the same kotsy from UrbanToronto?
