They might have a "soft opening" during that time. With this just being a makeover to a ride, I am not sure if this will be something they do or not.
I would ask the Team Memebers outside of the ride if they have any plans to do soft openings that day. Even if they say no, check back from time to time. Back when Spaceship Earth was getting a makeover at Epcot, I camped outside of the ride for nearly two hours because I heard rumors (and noticed a large numbers of employees hanging around the area and going behind the work walls into the ride). After all that waiting, and being told they were not going to do a soft opening, they did! However, by the time I got off the ride, they had already closed the line and put the work wall back in its place like the soft opening never happened!
Anyways, I can't wait to see this! Don't know if I am going to be able to manage a trip to Universal this year (still trying, but the E3 trip is costing more than I thought). Hopefully sometime before next summer for sure!
