I went to Passholder preview day yesterday. It was a bit chilly and damp, but it did not stop die hard wonderland fans from showing up.
I think people realize that the rides have all been sitting for 6 months outside in the winter elements, and don't seem to mind that coasters and rides need a bit of a break in to get running reliably. Passholders seem grateful that they get invited to a preview, and are excited just to be back at the park. The park was well staffed, and everyone i saw was friendly and seemed excited to be there.
It was a funny canadian thing that just before dropping the rope where i was, the security guard asked people please not to run, and they complied and behaved themselves....
I went to get an early ride on Leviathan, hoping that people would all be waiting for yukon, which proved to be true with abut 2 trains of people waiting, but they were still sending water dummies around. Instead i went on Wilde Beast. They Have put some new track in, but it is still bumpy in parts. It flew around the track with the wet rails. If you can't tolerate bumpy wooden coasters, don't ride it, but i had fun. The ride ops were inviting people to reride if their seats were available, so i did it twice. I got a ride in on NIghtmares and then Leviathan was opened. Got a great back row ride. Maybe it was wheel heaters, or the 'snow tires', but the ride ran great, and booked it around the cold track.
I got an almost walk on ride on Vortexx before passing by the new ride. It did not start testing until around 6:30 and started taking passengers close to 7pm. Thousands of keeners eagerly waited in the damp cold for a chance to ride on the first public day. The lineup filled the station queues, spilled through the plaza, across the bridge, up the hill, past the diner, past windseeker, past the games and to the carousell. Good on them, but I will wait a few weeks and come back on a quiet day.
The station building is really nice, themed to the Striker mining company. It also has a plaza nearby where you can stand under the final helix and watch the trains come overhead. The track interracts with the walking paths, and offers great views of the coaster.
This is the second train to depart. They seemed to be taking a long time to dispatch trains. it felt like 10 minutes, but looking at the times on some pictures it was closer to 7 min. There were lots of staff to talk to people in the line, and pass out new park maps. They said that if people were in line, they would stay open until they all got to ride. At that rate, they would be there the next morning so i don't know how it worked out. Good luck!
