If your planning to visit WDW, take my advice and come in september. There has been no crowds for 3 weeks now and you can walk almost right on any ride you want. One day at MK the posted time for Space Mountain was ten minutes at 11am and again aat 1:30 pm.
My recent visit to EPCOT had me walk right on Soarin and Finding Nemo. The parks are sooo much more fun when they aren't so busy.
Here's a few pics I took.
