I've always found thorpe park really busy most of the season , The staff on the ticket booths are working flatout and as fast as they can . I renewed my annual pass last month and my friends collected there new ones and we got all done in about 10 minutes which I was amazed .The earlier you get there the better , you don't expect ever to turn up 10 minutes before opening and expect to get your pass and go straight in before opening to time with the queues .
