A few more things to see,
Wild Arctic, 2nd Shamu show in dark, Odyssea, Pets Ahoy!, Sky tower, Tropical Rain Forest, Dolphin Nursery, Stingray Lagoon, Turtle Point, Clydesdale Hamlet, The Waterfront, Shamu's Happy Harbor, Budweiser hopitality centre this one takes a while

, there will be some I missed.
Not to mention
shopping, eating (Their cherry chocolate cake and carrot cake is very nice)
They also offer at least another day free (6 days unlimited admission for cost of 1 day at the present time) so consider going in again and doing Adventure Express Tour takes 6 hours and is superb, we are doing it again in August.
I would love to watch someone try to do SW in half day.
