I think WnW is going to start testing the virtual queue/queue-less system soon? There are stands set up around some (all?) of the attraction entrances at the park. I don't know for sure, but based on the discussion earlier this year, it seems like a huge possibility.
I'd be interested to try this. My slight concern with it going into an existing park, particular one like Wet n Wild which was built 40 years, how will it handle the extra people who are no longer waiting in queues? That's going to be one extra busy wave pool and lazy river.
