They have a new thing for rides now where you get a "Fastpass." That gives you a certain time to come back for that certain ride and you get a shorter wait. So the people who have been waiting 45 minutes for their 30 seconds of pleasure really dislike the "Fastpass people," unless they are one. So we took our Fastpasses for Space Mountain and as we were passing the "common people" a little kid (4-5) reached out at me and said "I hate you people!

"
Here's a hint: GET THE FASTPASS.
Seriously, you get the fastpass, and the time you're usually given to come back and cut everyone in line is the same amount of time those people waste standing on the line like chumps. You get the use that time more productively.
OR...you get the fastpass for a really busy ride, wait on line, and as soon as you get off it's usually time to use your fastpass so you can go right back on.
OR...you get the fastpass, and once your designated time to come back has arrived, get another fastpass before you get on the ride, and by the time you get off the ride it's usually time to use your next fastpass.
OR...if you're at MGM (which is now Disney Hollywood Studios), and there are lines at Tower of Terror and Rockin' Rollercoaster, get a fastpass for one, wait on line for the other, and by the time you're done with one, you can go straight onto the other with your fastpass.
OR...wait until the end of the day at Animal Kingdom, because that's when the park starts to empty out and the lines dwindle down at Expedition Everest.
OR...hit the rides during the fireworks or the parades, because the lines are usually shorter.
OR...be lucky like me, and an end up winning a Dream Fastpass to every ride in the park in the Year of a Million Dreams contest. That happened to me when I was there last month.
I've been to Disney World 8 times, I know all the tricks. That's the key to enjoying yourself there.
