Mystify runs nightly after Memorial Day so you might want to wait till Tuesday to go then. The best areas to watch it from are the Waterfront area or over by the Spice Mill restaurant from the outdoor seating area. They put up 2 "walls" over the water to project the images and shoot the fireworks from basically. It can be seen and heard best in those 2 areas.
It used to be we'd go to Shamu Rocks and head over as fast as we could to get a good spot to watch from, so it will seem funny not to have Shamu Rocks before the fireworks/watershow. Wonder if they will have a special night show somewhere else.
If they start the summer night show of Clyde and Semour, they change it from the daly shows and sort of satire some of the other shows in the park. Show is funnier than the daytime shows usually. Worth going to a 2nd time.
