We are coming in October and would like to see the mermaid show and kayak down the river. Is it possible to do this in one day? Is there a package deal for this type of thing?

The mermaid show is in with the cost of Park entrance. Kayak rental is separate but in the same parking lot. And yes you can do it in one day

If you scedule this out correctly, you could get this done in a day easily. Im not so sure about any packages that include what you're looking for.

You would be able to do this in one day but you need to time it right is all. As for the package deal you need to pay to get into the park and the shows are free. I haven't looked into kayaking though.

It's possible. The mermaid shows takes most of the day the are 2 different ones and you need to stand in line for at least 30 minutes. You can look on website for time's and schedule your day
