Is there music playing at the water parcs pools and/or slides? In general is there music playing on some places or everywhere?

Yes, there is music in certain places, not throughout the entire park and sometimes there are events with bands. Check their website for park times and events.

There was music playing over speakers by the free swim pool and adult water slides, some slides had there own music. Some places had music, most kids places didn't if recalling correctly. We were only on the waterpark side tho.

There's music playing in certain areas, but not throughout the park. Sometimes, there are even live bands!
