Not a whole lot has changed at SWO recently. The most notable things that are occurring at the parks now is Journey to Atlantis getting its drop re-tracked this week, and Summer Nights is approaching. Internally there hasn't been a lot of information passed around about what the new nighttime killer whale show will be but I can say for sure I am excited to see what it is.
Oh also if you really like the animals at Sea World like I do they did just have their Weedy Sea Dragons at Manta start showing eggs, which is a very rare occurrence for any aquarium.
