We just tried to use Ridemax for the Friday after Thanksgiving. Frankly, the park was soooo crowded, we didn't end up relying on the Ridemax schedules. It took at least 20 minutes or more to get from Main Street to New Orleans Square. The crowds were impossible. We pretty much just gave up getting on rides. Luckily, we had reservations for Blue Bayou for lunch and Aerial's Grotto Princess meal for dinner. It was a relief to escape the crowds for two pleasant meals.
Also, it was so crowded, we decided early on that we would try to see some of both Disneyland and DCA, as no one in our group of 11 wanted to brave the parks for another day. At least as far as I could tell, Ridemax couldn't generate a schedule that involved both parks.
In any event, I think Ridemax might be helpful for a moderately crowded day. For a holiday and the days around the holiday, I've decided nothing helps other than to avoid the parks completely!
