I used Ridemax in WDW and it is extremely accurate. That one you can build in parades and shows, which I found disappointing when I got the DL ridemax.
So even tho I think WDW ridemax works much better, I still say it is worth $15 to get you in and seeing your faves even if it is only in the morning. You do need to play around with it and try several options.
Also, they just expanded to the first week or so in November when we will be there. And they NEVER do Sundays - even in WDW.
