Welcome to the Ocean Dome

Ocean Dome has its own flame-spitting volcano, crushed white marble sand, and it also boasts the world's largest retractable roof, providing a permanently blue sky. Temperature, wind and humidity are closely controlled to provide an ultra-safe sea-side experience. Every hour, the volcano erupts and the hi-tech wave machines start up, starting a few minutes of sanitised surfing. Entrance costs US$50, which seems especially expensive given that there is a free, natural beach only 300 metres away. Imagine a beach where the sky is always blue, it's never too hot or cold, the water isn't filled with salt and pollution, and the surf is always perfect. Welcome to Ocean Dome, the world's only indoor beach. Now that is amazing! Given a choice, which would you choose, the real beach? or the ocean dome?
