I don't know of a specific link, but I would assume that the good times to go to WDW are very similar to good times at DL.
From my personal experience (lived an hour or two from DL my whole life) the best times to visit the park are as follows:
Mid September-November (prior to thanksgiving)- although park hours are shorter, the weather is mild and since schools are in session the park tends to be free of crowds. If you can stay for a long weekend you can see everything you want to see, even though the park may close at 8 or 9.
Early December- mild weather, low crowds, and BEAUTIFUL christmas decor.
Late January-Early March- anytime prior to the spring break season is a good time to go.
Those are the best times, in my opinion of course. You may be able to get cheaper hotel rates as well. I have experienced
Disneyland during peak times such as New Years Eve, weekend after thanksgiving, spring break, and summer...and it isn't worth it. You might have the park open later, but how fun is it to walk down mainstreet with people constantly bumping you and waiting in 2 hour lines?
Hope this was helpful and if you have any other questions, send me a PM. I am happy to help out!
