Agreed with Mom - the lens you are using isn't the best for that type of shooting - as it's pretty slow on the maximum aperture. Sticking with the widest 18mm end of the lens would be your best shot - that should give you F3.5 - you might consider using Aperture Priority mode to make sure it stays there. You'll probably have to crank your ISO to 6400 - it'll get a little noisy, but might give you enough light to get something usable out of Pirates, Spaceship Earth, Small World, etc. Peter Pan and Haunted Mansion might be just too out of reach for that lens. If you shoot in RAW mode, and set your shutter speed manually to 1/50, aperture to F3.5, lens at 18mm, and ISO at 6400, you could remove much of the noise, correct the white balance, and lighten the underexposed photos to something usable...but it will take a little work. If you use something like a cheap 50mm F1.8 prime lens, you'll have a MUCH easier time of it - that could mean the difference between underexposing and a good exposure, or ISO3200 instead of ISO6400, and a faster shutter speed to avoid blur.
