Yes and no. I've said it before amimals are as popular as ever. That's the thing aquariums have proliferated. Shark tunnels are a dime a dozen. Zoos have taken new habatats exhibits and gone with it. The animals are part of the SeaWorld Experience. Mako should have had a Shark Tunnel queue and the the coaster could have incorporated a acrylic viewing tube either right before the lift hill or at the final brake run before the station a drop into an open shark mouth somewhere along the run.
I'll say it again and again, a hotel with aquarium view rooms would print money a lobby with a Berlin Blu like aquarium with elevators would be part of it.
