The only way to ride Nemo is to be a DVC member with the blue card in hand or a Annual Pass holder. The cast member is checking. You can take 3 people with you per card. We just rode it over the weekend. It is not completely open yet, or this was my understanding. The line for this ride will be deceiving when it is open, there is a very large area for a line inside. It reminded me of Splash Mountain the way it is set up. It needs to be a fast pass when it is open !!!!
