Haven't used Ridemax, but have gone mid January! I'd say that as long as your trip doesn't include the MLK weekend, you really don't need a strategy. The best one (and it's free!) would simply to be at a park at opening, and then I can't imagine you'd have ANY trouble doing what you want.
If you are going primarily over MLK, then you might want to consider Ridemax (based on what others can tell you about it), just follow UG, or look at Tour Guide Mike which I think is a great source if you're flexible about where you're going on what days. If that's already set in stone, then I'd probably pass on his site at this late point! Either way, if you go that weekend, try to be early and you still probably won't have many lines!
