Lovely idea in theory, but will never work completely in a theme park environment. No theme park has enough space to have over 10,000 guests roaming and never having to wait for an attraction.
Genie+ and Lightening Lane at the American Disney parks is a compete disaster IMO. It's turned the parks into rich peoples playgrounds and even they have awful times with the system and it is is near impossible to wait less then half an hour for even the smallest rides.
Europa Park which still runs it on some of the bigger rides, and is a park that could maybe do it, still has a stand by line.
Virtual Queuing falls apart whenever there's even a slight issue. Ride breakdowns, reduced capacity, guest action.
The real issue is theme park guests turn their brains off when they get beyond the front gate. The more barriers put in the way, the harder the day becomes. It becomes a system where those in the know such as AP holders are the ones that get the real benefits but the average guest will never really feel like it works.
The closest I can relate this too is the RAP queue for disabled guests. In theory, that could be a wonderful system and really benefit the guests who are unable to wait. But that is completely open to abuse. People hate to hear this but it's the AP holders, the ones who know how to get around the system that are making that whole thing a nightmare for everyone to use.
