||In order to manage the quality of visitor experience, social carrying capacity has been prevailingly applied to the planning of contemporary parks and natural environments. The common underlying logic of the applications is that carrying capacity can be determined through the identification of management objectives and associated indicators and standards of quality. Indicators can be monitored over time and carrying capacity is reached once standards have been reached. In this study, visitors’ “reported queuing time” for using their favorite facilities in theme parks was adopted as the indicator. Accordingly, visitors’ crowding norms, the queuing-norm-crowding relationship, and the applicability of social carrying capacity to the management of theme park settings were analyzed and discussed respectively.
