Ticket works very well, just scan the given barcode then we were ready to enjoy the park full day. We came ontime when the park was open and it was during high season. The queue still ok to enter the park (10:10 AM), but queue for the ride quite long (especially in the afternoon). If possible, buy the DPA to save time (60-90minutes long).
Btw, don’t missed the lion king show!
