Got to ride Manta 7 times today. Ride wait times ranged from 10 to 30 minutes. It opened around 9:30. Did see they shut the ride line a couple of times during the day, but never for any length of time.
Important Note: LADIES, if you have shoulder length or longer hair, be sure to put your hair up. Saw a lot of pictures (including my wife's first ride) where the ladies had their face completely covered by their hair.
What surprised me about riding in the back, was not just how many G's you pull in the pretzel loop, but HOW LONG you pull those G's. And to everyone who says it "looks slow", you haven't ridden it. For a flyer, the pacing is great.
Sea World and B&M were smart about building this "attraction". Instead of building the biggest, tallest or fastest, they said let's take a proven design, that hasn't been built in Florida, and put a true Sea World spin on it. MISSION ACCOMPLISHED!
