Went this weekend - it was crazy experience but inconsistent.
Traffic in - even Saturday at 4pm was an hour on the causeway. An hour just to get to the parking booth! We did not have Fastline - so we focused on mazes. MF was only a 25 minute wait by 11pm and Magnum was a walk-on by 8:30pm - so we did that a few times - still an epic ride in the dark in the back. My kid had never experienced true ejector air before.
Scarezone waits were insane for cornstalkers.
Sunday - had platinum entry plus fastlane plus (free due to season pass renewal) - was able to get in SV, maverick x2 by 11:30am.
Then it was a gong show - Gatekeeper down for the day (rumor is reopened after 8:30pm but we were at the top of the park and it was near closing time so too much of a risk to run down instead of night SV), top thrill after an hour fast lane wait broke in the station, waited another half an hour for a reopen that never occurred. ride opened up again five hours later (we got in after another 45 fastline wait)
Valraven, and Maverick fast line was decent - not that long of a wait. But MF had fast line line equal to regular and SV was still close to an hour and top thrill more than an hour.
The long and the short of it is that we still had a great time. The haunt stuff was good. My kid's first time on the 52 inchers (though we didn't get gatekeeper). We didn't have a choice but to face the crowds (long weekend needed for drive back, had to take advantage of fastlane promotion, kid wasn't tall enough earlier in season, etc).
Only real complaint is the fastline - we were so excited to take advantage of it to really enjoy the rides, only to find out the lines are still crazy long. They really need to reduce the number of fast lanes they sell, at $120 plus it is not right to sell so many that are still hour lines. There was nothing VIP about it. Since we used our entitlement it wasn't the of the world, but if i paid out of pocket i would have been really disappointed.
PS. Windseeker is the dumbest name ever. Why call a ride windseeker when it can't ride when there is wind? Shouldn't they call it Windfearer?
