Plug is also pretty bad, but you won't get blisters and sore thumbs when you're finished. You might however get your hands trampled on as you're trying to find where the hole was and plugging it back up. This normally isn't that bad of a job, but keep in mind that this is during the night parade, the lights are still OFF in your area, so you're feeling around for the hole in front of a crowd of people eager to run ontop of you and head towards Splash Mountain.
Stanchion isn't that bad, just tiring after you get done with Liberty square and then you still have Frontierland, which by that time you're tempted to use those things to ward off those guests trying to cross the line before we're finished rolling that area up.
I have no idea why Jungle skips love N-PAC. I much prefer quieter cruises at night with people that actually want to hear your corny jokes, but that's just me. Some of them just get so tired of Jungle they want out, which I understand. I look forward to my night cruises, and use that to get me through the day of the below-average boatloads of guests. Good times.
I worked one parade shift while I was at Disney (2007). It was Easter week, at the Magic Kindom (it was a day that they were so busy that they were restricting who was entering the park), and I was stationed by the Liberty Square River Boat. I got to be the person that placed white arrows on the ground in tape that directed people where to walk. Once that was over I got to make sure foot traffic kept moving and people weren't sitting on walls. Although it was a great day, I couldn't even count the number of times I was told I was running someone's day because I wouldn't let them sit on a wall and watch the parade. When it was all over I tried not to get trampled as I removed the arrows from the ground!
