Yup! I just did for my most recent trip (we were staying at Disney). We got a 1 day, 1 park ticket. It was around 90 dollars from
UT. I may get a 1 day, 2 park ticket next time but I'm not sure. Maybe you can help me with this? Is their "park hopper" like Disney? I read something about a hand stamp but can you just scan your ticket again?
