I would think that Sundays will probably still be busy. If Remember, Dreams Come True is showing on weekends, then Friday through Sunday nights will be busy.
Other than that, though, there are no special promotions to attract the locals, so I think the weekdays will probably be pleasant.
(As far as Ridemax goes, if you absolutely want to do as many rides as possible, it is probably useful, but I found that when we used it, we really spent precious little time just sitting back and enjoying the ambiance, which is too bad. I know the basics of crowd flow, so if I had it to do over again I think I might have chosen not to use it--and we went around the 20th of June, when the parks were considered to be packed.)
