cemeb4dk, you can use either or both, the online version or the download version. I know everyone likes to access info via phone or mobile, but the download version contains a lot more information.
gacsmom, as far as I know, Mouse Wait is only a wait time projector for the length of time you wait for each ride, whereas Ridemax is a custom itenerary program that includes years of information and statistical data.
In my opinion, they are two different things, but I've never used Mouse Wait so I can't say for certain what it includes.
My issue with TouringPlans is simply based on inaccuracy of their touring plans and numerical attendance ratings, in my opinion. I don't have a problem with their Lines app. Some like TouringPlans, it has a loyal following at WDW especially, but I found it to be just as inaccurate at WDW as it is at DL.
I've been accused of working for Ridemax, so I try not to sound like too much of a fanboy, but it's just such a great product, especially for DL first-timers, I can't help but recommend it.
