We just got back from DLR last night, Cheryl. The lines for Nemo were ALWAYS dauntingly long. We rode it once on our early entry day, but we didn't make it back to the ride until 8:20am as the ticket lines outside the park did not move smoothly going into the park
When we got there, the wait was 1 hour & 10 minutes and it was exactly that. The wait was worth it, but we didn't do it again.
