I went to Busch Gardens yesterday to ride Phoenix Rising. I was able to get 1 ride before previews ended and then some more rides during Passport to Thrills.
It's a mostly tame coaster as expected but in the back of the train, there were some more forces than I was expecting. There was a slight rattle but less noticeable than Penguin Trek's and didn't take anything away from the ride. I also thought it was better than the 2 Vekoma family inverted coasters I have ridden at Fun Spot Orlando and Kings Island with steeper banked turns on Phoenix Rising.
They built a very small queue for the ride. It can hold around a 20 - 30 minute line at the most. There is only 1 train and slow dispatches with everyone from the previous ride needing to exit before the air gates open for the next train. Combined with this being one of only 2 coasters in the park without an inversion (besides the kids coaster), it's probably going to be very popular with long waits once it opens to the public.
The Passport to Thrills party was also great other than them not letting people in until 6 when they originally stated you could check in at 5:30 which caused the line to go past Scorpion. They gave out first rider buttons (also available during previews), popcorn, drinks and a Phoenix Rising fanny pack that was originally supposed to be available for all pass members until the end of the month. There was also a DJ and free face painting.
