What works really well for people with motion sickness?

So, I want to go to Disney World with my boyfriend on holiday this August but it's really no fun if you can't go on the rides. lol. So I'm wondering if anyone knows of anything that REALLY works for bad motion sickness. I've tried ginger pills, ginger snaps and ginger beer but only for road trips, does that work for rides also?What works really well for people with motion sickness?dramamine
