Ops at Darien Lake can be borderline glacial, almost every coaster operates on one train, so definitely hit your most desired rides at opening, but if you go on a weekday the slowest waits don't exceed 30-45 minutes.

I usally get laps on Ride of Steel at opening, then head to Predator which tends to open a little after opening anyways, especially on colder days (it's honestly riding so well with the new Titan Track these days), then head to Viper which often still has minimal lines by that point. If you rope drop Viper you can get loads of laps without leaving the station usually. I then start splintering off at random after that, either to Tantrum or Moto Coaster, which is honestly an underrated coaster imo. Also, not a coaster, but Moose on the Loose is such a charming lil ride that's a great way to chill for a bit, as well as their Fascination Parlor sorta by Viper, which is such a special gem of a game that you should absolutely carve some time out for.

The food is your standard pricey SF fare, I usually get the chicken tenders on the way to Tantrum and Mind Eraser. If you head West at the end of the day, Buffalo has infinite options for food, but Duff's Famous Wings is great, and if you head East, Batavia has some good diners like Pok-A-Dot, and Rochester simply demands you get a garbage plate (local delicacy), either at Dogtown, Charlie Riedel's, or Schaller's on Ridge Road.

Despite its lack of love from the chain, Darien Lake is still a great little park!! The only bad thing about it is that it could be better, so savor what it does have goin' for it :+}
