While the theme parks may be busy at Easter there are some tips to get the best out of it.
First, buy a couple of books about Orlando, there are loads of them like "Brit Guide to Orlando"

These give tips about the best way to "beat the queues"
Some I remember from other books I read.
Try to get to the park before they open so you are one of the first in the park (while it is fairly empty)
Most people walk round parks clockwise (turning left as they come through the door) so go anti-clockwise to avoid the early crowds.
When they arrive most people go on the rides near the entrance. If you get their early head straight for the back of the park and you will get on 2 or 3 rides before the queues build up.
