Tokyo DisneySea's newest area, Fantasy Springs, opened on June 6, and we were eager to visit and experience it. My friends lined up (well, just them, haha) as early as 4 AM to secure DPA and standby tickets upon entering the park.
We highly suggest planning your day and assigning someone to buy the DPA and secure the standby tickets. Fortunately, since we were so early, we managed to purchase 1 DPA for the Tangled ride and 1 standby ticket for the Frozen ride. This is the only way to enter the Fantasy Springs area.
Also, note that you can only get 1 standby ticket per hour, so plan which ride you want and make sure to get one quickly, as tickets run out fast!
