Recently while at Hollywood Studios we went and hung out in Toy Story Land to ride Slinky Dog Dash. Now we got to the park around lunch which if you ever read about us visiting the park we recommend not doing this. We always say go early and come back late. While there this day the wait time for this roller coaster was over 2 hours. I have seen this ride over 3 hours at some points. My recommendation is alway get a fast pass if you can. If you are unable to get a fast pass my recommendation would be to get to the park when it first opens or go late and get in line before the park closes.
I remember when Seven Dwarfs Mine Train ride opened we waited over 3 hours for the ride. Now to be honest the reason we waited so long is as we waited in line at the time the wait was only an hour. As we got to the front of the line rain along with lightning forced the ride to stop. Now a normal person would have just gotten out of line and left but not me. I made my way all the way to the front and there I decided that I was not going to give up my spot. So the moral of the story get a fast pass don’t waste 4 hours of your 12 hour day waiting on a 45 second ride.
