It is very convenient. For a family trip, we selected two attractions in Okinawa and directly purchased a package. The cost is more cost-effective than buying them separately. You can enter the Churaumi Aquarium by scanning the QR CODE. Although you need to exchange for a physical ticket to go to the Okinawa Cultural Kingdom, you can do it online first, so you don’t need to queue up. You can directly go to the counter to exchange for a physical ticket and enter directly. There are quite a lot of attractions in the package, and you can change the itinerary by yourself before the opening, which is quite flexible.
