i hope they make all the attractions like radiator springs racers. it works really smoothly--you get a fast pass that's valid after about as long as the line is. so lets say line is an hour, fast pass works in an hour. everyone waits the same mount of time, some ppl are just waiting elsewhere and not in the line.
although a GAC won't let you skip the lines, they're very helpful. the alternate lines are usually less dense, and in some cases (like space mountain) there are places where you can sit and wait. good luck and have fun!
I LOVE that place! I used to live in los feliz and all throughout middle school and early high school, my dad would take me here for a special treat when I got As in hard subjects :) ahh, memories. try mickey's hat! if you finish it all, they give you a special button!!
