As Al has stated in his article, Finding Nemo: Submarine Voyage is set to open 4th of July weekend, 2007, and to soft open around the end of June.
4th of July weekend? This gives me a heavy sense of trepidation, even with So Cal's blocked out...there's still the soft openings, which is more likely when the crowd of AP's will show up. The ride's capacity is rather limited, and there's the question of where that hideous line is going to go.
So, I have a suggestion. What if Disneyland sent out special soft opening tickets to APs, setting aside to be used once between 1-3 days, depending on which AP one has? Premiums would have the first offering, then the Deluxes, etc...and once that's over anyone could ride during soft openings. No one else would be able to ride on set days. I think this would vastly help any line congestion scares for the soft openings of the ride.
