I was there today as well. I got to the park around 12PM and waited in front of the ride area which looks INCREDIBLE, by the way.
I talked to a few of the GM's around the ride and 4 out of 5 said the ride would be soft opening today. So I decided to stick around. At 1:30 or so, the ride started testing.
At 2:25PM the ride opened, and I was lucky enough to be on the first train, front row, of the public. That makes 2 for 2 for Sea World.
The ride itself is wonderful, it really does glide and play with it's surroundings perfectly. On the outside seats of either side, in the back row, you do get you a little wet from either the waterfall, or the water skim.
Best row for me was the back, you get so much G-Force, much more than on S:UF's. But I heard from a few people that Tatsu is better, but that is probably a given.
The inside of the queue was beautiful, with the tanks of fish and rays. Along the queue you can also find many "Hidden Manta's" just like the Hidden Mickey's at Disney. I think I found about 8.
I got to ride four times, twice in back (Left and Right side), once in row 6, and once in the front. The wait was never more than 25min.
Great ride, I hope to go back on Monday and ride it again! Pics may or may not come soon, my camera is giving me problems.
SeaWorld defiantly received a winner though!
