How much to rent cabana? And is there places where families can get together enjoy pool area,?

I went for exchange

You need to contact them directly with the specifics. Dates, etc

I believe that the small cabanas rent for $160.00 for four hours and the large cabanas rent for $200.00 for four hours. The best pool for larger group gatherings would be Harmony Grove pool. You do need to have a reservation or be an owner with day use privileges to use the facilities.
