3 sounds about right. Its not like Space Mountain where there is a fairly tall height requirement so that little kids cant ride it. Im guessing there will be no height requirement on Nemo which means all the little ones will want to go on it which will deffinately add to the wait time... (does that make sense???)
Also the fact that is a going to be a new ride, and EVERYONE will want to ride it. I would guess the first one and a half years the ride is open the line will take forever, only because people will want to go see it, and especially the people who don't go there much. Another thing is that the older generation remembers the submarines from before, and will also be anxious to see how it has changed and whatnot. I am guessing, like people above said, probably 4 hours for about 1 1/2 years.
I read on an Al Lutz art that the ride cap was 1300 per hour. That would mean it has one of the lower ride cap's when compaired to rides in both parks.
The "Rocket Rods" line was around 4 hours when I queued up on opening day in 1998. (boy was that not worth it.. I want my May 22nd Back!!!) I would think the cap on that ride was similar, which should mean that Nemo would have a longer wait time because of it's popularity with the younger audience.
I agree on the 4-5 hour wait. I'm curious to find out exactly how long the line will stretch. Do you think they'll try to have it wrap around Fantasyland and keep it within the park, or do you think it'll just go through Tomorrowland and down Main Street USA and out the doors?
If it doesn't have a fastpass, it will probably be long. I'm no expert, so I will make no guess at length. However, I seem to remember that even before the sub went down (and when they weren't as popular) the line was still 30-60 minutes on average. So, if memory servers right, it's not going to be a pretty sight, but I look forward to riding it.
Stalking is when two people go for a long romantic walk together but only one of them knows about it.
