I went on the Wednesday before Thanksgiving (11/23) and I would say about half of the coasters were closed. The list of closed rides included Riddler, Scream, Superman, Wonder Woman for about half the day, Goliath, Full Throttle, Viper about half the day, and Ninja.
The only rides running consistently all day with at least two train operation were Tatsu, Twisted Colossus, West Coast Racers, and Gold Rusher. And surprisingly Lex Luthor, CraZanity, and all the flats were running fine too.
Coasterbill hit the nail on the head. If you need to close during the week during the off season (especially considering their volume of coasters and rides to maintain compared to every other SoCal park), so be it. But open most (if not all) of your rides when you're open, and when you're charging an arm and a leg for admission and parking now.
Six Flags was totally killing it through the pandemic the last couple years and we were all laughing at Cedar Fair, and it feels like the total opposite now.
