i had a chance to ride it twice last week...the first time we waited around when we saw cm's moving near the fastpass signage...there were about 200 people waiting with us and we were able to ride it in the first 10 minutes of it opening...this was after a wait of about 1/2 hour....
the second time we rode it, we just stumbled upon it after doing ellen's energy ride and were able to ride it with a 20 minute wait or so...but this time, the ride did breakdown while we were in the cabin...the cabin went dark and the video started but we were told that we did not yet have clearence for liftoff...we waited in the cabin for about 10 minutes until the doors opened...a cm came to our cabin and escorted us out and to another centerfuge (sp?) and we rode with no wait...
it is an incredible ride and is not to be missed is you have the opportunity....
remember, it is not officially open and you cannot count on it being available for you to ride but it seems like if you have the time to wait when you see activity at the pavillion you should be able to ride it...
good luck and have fun!!!!
