Just returned from Disneyland, enjoyed. But still favor WDW, which we have had season passes for last 10-12 years (live in Texas)and go 3-4 times a year. The weekend of the 11th will be big crowds at both places. Should be slow for Tuesday thru Saturday (14-18 Nov) and big time for Thanksgiving week.
Best times for WDW is mid - late March (avoid Easter when early), Late April thru May, last 3 weeks of September, and three weeks after Thanksgiving. January use to be great, but South America empties into Orlando in Jan/Feb.
Been to Disneyland probably once every decades starting in the 60's. I am not a fan of California, especially Southern part. Now Monterey I liked, was there attending the NPG School and then the Commander's Course
(also only place the wife likes).
The wife said that she'd go to Disneyland, since the YOUNG ONES HAVE NOT BEEN. Cars land and Frozen she really enjoyed, plus Fantasmic was better than at WDW.
So from a "rat chaser" you can't go wrong. Give the kids a look at the other park.
