Annual pass discounts for Discovery Cove

[Trex-lib]

We are going to Discovery Cove and Sea World end of next month. Is getting an annual pass for Sea World worth it to get discounts on Discovery Cove? It says 30%, but didn’t know if that was all the time. You can’t see prices until you buy the pass. Are there other discounts for Discovery Cove that make it worth it. There are 5 of us. 2 Adults and 3 kids. Is any annual pass person willing to look or could they give me that info if I call?
I’m just trying to save as much as I can without it becoming too complicated.
Thanks!
