It depends. You can still get MUCH faster film than any digital camera is capable of (most digital cameras are roughly equivalent to ISO 100 film, some of the better ones are finally reaching ISO 400 equivalency), which is good when trying to take a picture on a moving ride. However, a digital shot that doesn't come out isn't wasting anything.
I've switched to all digital myself. With the 3.3 megapixel (and better) cameras that are available now, it's pretty much IMPOSSIBLE to tell a picture is originally from a digital camera if you decide to get a print, especially with typical 4x6 prints. Heck, I had one digital shot I took blown up to 20x30, then framed it and have it on the wall in my dining room, and it looks GREAT (a web-sized and stamped version of the shot is at

So it depends. For best results on-ride, film is probably still the way to go, but digital cameras are rapidly closing the gap, and are less wasteful.
Standard.disclaimer:
Always follow park rules regarding camera use. Violating rules and sneaking cameras on rides is endangering yourself and others. If you get thrown out of a park, or your equipment confiscated, then you get what you deserve. When allowed to bring cameras on rides, always make sure you have a SECURE way to hold it, to ensure you don't lose it.
