save your dough on dining with shamu. I went in oct 2005. it cost $32 an adult. you are seated in two rows of tables that line a small pool. I was seated against teh pool which was complete luck. many people who were in the second row were yelling at the wait staff to be moved to the "inner" row. I am sure SW will at some point ask more for $$ for "premium" seating.
it's a decent all you can eat buffet. the server brings you the drinks. there is a short movie, and then a short demonstration with a whale in the pool. it was because you are much closer than the regular show. the jumps are done far enough away from the diners that you do not get any splash.
it was very hard to see anything from the outer row, so you either stood up to see or you got a very limited view.
i got some great photos. at the end of the show (about 30 mins) the whale swims right up on each section of tables. many people jumped from theirs thinking they were going to get soaked. you dont, but it was funny to see.
then, you are done. you go next door to the stadium to watch the whale show...
shamu rocks seemed to be the same as the daytime show, just done at night.
