The experience was great! I exchanged it for Okayama Castle and Korakuen Garden, plus a tourist pass. Do your research and don't exchange it too late. Confirm the exchange location and get your voucher. The exchange location for Korakuen Garden is at the museum, so you need to take the receipt to exchange for a ticket. The tourist pass also comes with a map, but make sure to calculate if you have enough points to use. Overall, it's a great value!
