We are going to DL from Nov 10th-17th and wanted to go to KBF, which day would be best (least crowded)? I'm thinking either Thursday or Friday but would prefer the Friday unless it will be really busy.
Weekdays for any theme park seem to be less crowded, so try going on a thursday, friday seems like it'll get packed later on as the evening goes.
I've only been to Knotts a few times in my teens for a special night only for Target workers and their families, so I haven't been to it when it's very crowded.
But if you get the chance, go and see "Mystery Lodge", it's a great show if you get tired of the heat or just walking around.
