I just confirmed our visit with them. I received a PDF note. It appears there are two options if I'm understanding it correctly. I wish I could copy and paste it here. The PayGo option is $45 per person and includes chairs and an umbrella and spending $45 in food and beverage.
We are doing the day pass. It is $70 pay in advance or $75 day of. We are paying when we arrive. The $75 includes use of water toys (kayaks, SUP, floats, etc.), 3 drinks, 2 waters, chairs and umbrellas, lunch with sides and dessert.
If you have more questions, contact them through their website. They have been great with communication.
