yep, the universal express unlimited is available, it's just slightly "hidden", because you have to first choose the one time universal express first.
If you don't want to take the tour, then the VIP doesn't really make much sense, since that is generally the highlight (that and the lunch).
Please note that there are four possible lines at universal:
1) Normal queue
2) Single Rider
3) Universal Express
4) VIP (but only with guide present)
#4 is generally the same as the "Universal Express", but they have the flexibility to skip parts of the line as needed. One common thing is if "Single Rider" isn't running, they will use that line. However, the tour guide MUST be with you to take advantage of this. Once the tour is over (or before it has begun), you just use Universal Express line.
I believe there is a disability pass as well, and that uses the Universal Express.
