Those are interesting ideas. I'm sure they could put together a really interesting aquarium in a decently large space as long as it was only an aquarium but Tiger Valley said that's not the overall goal it would seem. Indoor play area I think would be the least desirable outcome. It is so far away from everything, unless they wanted to rent it out for birthdays or something I just don't see how it would work and it wouldn't seem to keep with the mission. Quarantine area might have more merit.
