You know, you may be able to get some shots on the brighter lit parts of certain rides depending...I know when it's more crowded they tend to make the boats in POTC go by a lot faster than when it's slower. So it's harder to get the shutter speed up high enough without the fast lenses. But, when it's slower (crowds), they tend to let the boats cruise by at a much slower pace and when that happens it's a lot easier to get the shots in the darker areas, so I can only imagine you may be able to get a few of the brighter lit areas. Also, IASW is brighter lit. Haunted Mansion may be out of the question. If you only have the kit lens, take a look at the crowd levels. If you go on POTC during a show/parade or at night it may be slower and have lots less people on it than during the day when everyone is trying to escape the heat. Less people = slower vehicle=slower shutter+more light to try to capture a shot or two. Otherwise, just enjoy the ride as best you can. Good luck!
