Any dolphin experiences in Belize?

We'll be traveling on the Breeze in July to Cozumel, Belize, and Roatan. Trying to determine where we might have the most affordable option for a dolphin encounter. Doesn't necessarily have to be a swim with the dolphins, but something that would allow my 10 year old the opportunity to pet them, see behaviors, etc.

I've done Dolphanaris in Cozumel and it was great, but looking for more budget friendly options as that one was around $125/person.

Not in Belize. There may be something in Roatan, but Chankanaab in Cozumel will be the least expensive that I know of for sure.

its been proposed in Belize but there was a huge backlash against animal cruelty.
