I have not done over easter either -- but I had my sister in law go over easter using TGM. she got a day by day break down of each park, where to go and where not to go,, and why,, this was done for both the morning and the night. Also-- there were articles written specifically about how to survive easter, but I dont really know what they were about -- just that she thought they worked beautifully.
Now, every single day in 2006 is broken down day by day, park by park, morning and night --from Jan to July. I am going in August again this year, and august least crowded charts and itinerary planning thingy should be out soon, because august park hours are now out.
I do know he has tons of stuff for Summer survival-- not just drink lots of water either-- but how to get a last minute dining reservation, and how to kick your touring up a notch to handle those big crowds, specific advice about touring each of the parks during the summer and all sorts of other things too.
