I really liked the itinerary; we happened to see the sunset 🌇, which was beautiful. The coach helped take photos, but they weren't professional, so the pictures were just average. Because our schedule was a bit delayed, we told them we might arrive a little late, but we were sternly informed that if we were late, we wouldn't be able to participate at all and wouldn't get a refund, and that we absolutely had to arrive before 4:00 PM. So, we rushed to get there on time, only to still wait for almost half an hour at the site before departing. We also saw other groups who were late still being able to participate, which left a bad impression. You can bring your phone or camera to take pictures while playing. Your pants and underwear are highly likely to get wet, so it's recommended to bring an extra pair. They provide slippers for us to change into, which is nice. You might want to bring an extra towel to dry your feet, as it's more convenient when changing shoes after getting ashore. Overall, I recommend coming to Okinawa and definitely trying this activity.
