Studio 407's design involvement at the Living Seas Pavilion is also interesting. They're "bread and butter" is restaurant theming, attraction queues, etc. And we all know the Living Seas is due an interior refresh.
I found a South Florida Water Management District permit today for a partial draining of the lazy river for maintenance purposes.
