Wanted to update on this. We went with the boat ride where they caught fish to touch. They only let the kids touch the animals who wouldn't be bothered by being handled before being rereleased. The more delicate fish were placed in tubs where the kiddos could get real close and see them but not touch. I thought it was very respectful.
Unfortunately, DD was sick with a cold that day. So she only enjoyed it a fraction of how much she normally would have.
