It'd be awesome to go innertubing through Splash...I mean if it were safe for that sort of thing which I know it's not. But to slowly go past the show scenes just relaxing would be awesome.
I also wouldn't mind walking the tracks of the HM while it's going (well the doombuggies could be stopped so I don't get ran over). I'd love to just sit and stare at the show scenes for a while. Not even to see behind the scenes, just to soak up all of the scenes without rushing by in a doombuggy.
