In the scenario that my previous reply was referring to, it was proposed that groups of three gondolas would arrive at a time, then later, another group of three would arrive. The fact that they would arrive in groups implies that there would be a gap between the next group, which would mean the system would not be an omnimover as we picture it at Disney, with a number of cars lined up, constantly being filled.
The system I'm envisioning this to be would act as an omnimover, but if there were dedicated gondolas for the resorts with nobody there to get on them, there would still be unused cars when they could be filled. It would be akin to the Haunted Mansion saying you could only use every second or third doom buggy because the others were reserved for some other use. It would cause unnecessary delays.
