I dunno. I know the per hour capacity is greater on HM and POTC, but Splash has always got the 2 hour line, and before FP it always had the 3-4 hour line. Even though you don't get that wet, I think there is just something about water rides in the summertime. Once Space is back up though, I hope it regains its title as most popular. That's the only one I would ride over and over and over as a kid.
i'd have to say peter pan's flight. the line for that ride is ALWAYS long. it's a classic next to POTC.
Seriously...that may be the longest line in the park. At least, it is everytime I want to go on it!
I think the most popular ride depends on the person, really. I mean, I know that there are going to be some rides that are more people's favorite than others, but I think most of us would defend to the bitter end our favorite ride as the most popular.
Speaking as one who has a framed, full size PotC poster and pirate themed room in her house, drink up me hearties yo ho!
