The ancient theatre is the longest walk of a Pamukkale visit. It shares the site with the terraces, so a second car is unnecessary. An early entrance is easier, before the sun and the crowd.
On an afternoon landing it is better to leave the bags at the hotel first, then go to the theatre. With a guide, the car waits for the finish time. The fare is not written until that wait is agreed. If Laodicea is added, we name the extra time separately.
