Just come back last night.
沖縄美ら海水族館 after 4pm only JPY 12xx (org. price 18xx), the 水族館 not big, just need to spend 1-1.5 hrs, suggest to visit the park, then go in the 水族館 on 4pm to save $$.
青の洞窟浮潛 worth to go, a lot of fish, good experience.
Rental Car can consider J-net Rent a Car, I got a Honda fit at JPY 15xxx for 6 days 5 nights (promotion price). But just remind the GPS is in Japanese.
愛一個人的優點而誠心接納他全部的缺點,就是婚姻最偉大的地方。
