Personally the way I used it the one time I had it was just did a cycle of every house from the back of the park to the front, starting with the lower lot, then to the curious george lot, etc, and then after that took some time to hang out and people watch in the scarezones, though you could replace that time with a show if you were interested in that sort of thing, then made another cycle prioritizing the houses I really enjoyed, and kinda just kept doing that until closing or I needed a break.
You can really do it any way you want, since with unlimited express its pretty much more than a guarantee that you'll get to do every house multiple times if you really want to, since Hollywoods line operations seem to favor express a lot more so you'll never have to worry about much of a wait.
Main advice I'd give is listen to your body, its a lot of walking especially if youre trying to marathon every house multiple times.
