Wow, thanks everyone for your thoughts, experiences and line tolerances. I'll be the first to admit last trip I was caught a bit flatfooted. I did the research, had our "must do list" and still ended up in a few 45+ lines.
Don't get me wrong, we used fast passes and were able to walk on a few of what we consider top tier rides, Tower of Terror, star tours, space mountain and a few others.
However, I did find myself a few times in an indecisive stupor, "wow, that's at 45 or 60 minutes, how long is the next ride." I ended up dragging the family through 1/2 of the park trying to decide if I'm being wise jumping in a longer line or if the "grass is greener" just a few more steps down the road.
Along with RSR, Dumbo was definitely work the wait (DD 5). The longest line we were stuck in was Mickey and Minnie's houses 60 min+ each. Minnie's with the, "almost there, oh we are headed to the backyard" was a bit of a morale killer. Me and the older two (DD 9 and DD 8) stumbled upon Mickey and Minnie on main street, and boy howdy was Sydney mad!
