How much does it cost, to swim with the dolphins?

I believe around $219+ tax.

You can book it through Old Town Trolley in St Augustine for $110 at their ticket booths

Yeah It's around $200 dollars but it's well worth it. You can also hold a canvas while the dolphins paint a piece of artwork that you get to keep.

220 ish. They give you a better idea of the whole thing on there website

But the interaction is about 30 cheapest and includes admission! Very personable! I loved it!

I believe it is like 220

We paid 199 but they give a VA discount. Don't remember how much that was though. We paid like 350 for 3 people
