just posted this in another thread:
We rode it on Saturday during our AP preview time and used
DAS. CM said the ride is not yet 'active' in the system to issue a return time, so he just let us right in using the Fastpass line after validating the DAS. The wait time was 30 minutes at that point - around 5pm.
its a very fun ride, very smooth, not intense as MMRR can be at times (like in the dance studio).
