Is this all inside? Or is some of it outside as well?

It is all inside

All inside, wheelchair accessible.

Yes it is inside. I LOVED it. Well worth it.

All inside

Be prepped to walk alot

Inside, takes about 2 hours for the aquarium and an hour for the wildlife exhibit.

It's all inside! And it's awesome

It's all inside. Shouldn't take much more than an hour or two to get through.

It's approximately 10 plus acres under roof. It's not a disappointment, there is plenty for adults and children alike. Make sure you feed the sting Ray's if they are still there!

Prepare to spend 3 to 4 hours walking inside.
