Allow me to throw this, I could see this acting like Paradise Bay from California Adventure, where it actually is still a nice and quiet place that people can relax at during the day, but can be used viciously for the nighttime entertainment. Even with special events done, Paradise Bay from what I've gathered is calmer than some may percieve, and that this may end up similar to that.
Just food for thought.
Are we sure this will be ready by 2018? Just wanting to ask that up-front, or if Universal has come out and said that it is happening this year for the new nighttime show (in specifics for opening timeline).
