I had a friend go the beginning of nov two years ago and she said they were walking on rides. Is that not how it is anymore? I know it will be more crowded becAuse of the 60th but i was hoping it might still be decent.
I think it depends a lot on what you mean by "decent". If you looking for "walk-on" for most rides, then I think you'll have trouble finding any weekend from end of September through end of December when that is going to be the case. At most, the first few hours after rope drop tend to be pretty quiet in the parks, but after that the crowds ramp up and remain fairly high throughout the day (on weekends).
What is the least crowded generally? From sept to dec. I want to hit friday once at least for fireworks but dont mind going on weekdays mostly.
The Parks Blog announced that the
Disneyland Forever fireworks would be presented nightly (except on MHP nights) during HalloweenTime. So if you go at the end of September through Halloween, you could see fireworks on any night of the week (except nights when there is a MHP, which has it's own fireworks show, but only guests attending MHP will be allowed in the park). F! is still running it's usual weekend-only schedule during HalloweenTime, so if you wanted to see F! you would need to work a weekend-day into your trip.
The fireworks schedule for post-HalloweenTime has not yet been announced. Normally, once the holiday season starts, fireworks are presented nightly, but F! remains on a weekends only schedule except during Thanksgiving and during the peak holiday period. I would guess that fireworks will continue to be presented nightly during the transition period (e.g., November 1 through whenever the holidays official start), given that they're presenting them almost nightly during the transition from summer to HalloweenTime.
So, for this year (I wouldn't count on nightly fireworks after the Holiday season) at least, it seems like fireworks are likely to be presented nightly, but F! (and Mad T Party) will be on the weekends-only during the non-peak season schedule. So adding a weekend-day comes down to whether you want to see F! (and Mad T Party) or not.
In terms of crowds, I think you'll find the lowest crowds during the transition between HalloweenTime and the Holidays (so early November), but the trade-off is that there might be attraction closures. If you're willing to forgo the weekend days, then I think there are more options (e.g., end of September, end of October, early November, and early December). None of these are likely to have "walk-on" attractions on all days, but short(ish) lines are not uncommon (except for the biggest rides like RSR, Space, HMH, etc.). I've gone in the end of September, early October, mid-November (after the start of the Holiday season) and early-December in the recent past. Early October was by far the busiest (with Gay Days and CHOC walk). The other three were all fairly similar in terms of weekdays (Mon to Thu). The weather was "best" in mid-November and early-December (cool, but potentially rainy).
