Just did the disney thing a week ago. Here are some tips:
--buy tickets on ebay
--buy premium lunch vouchers on ebay to do some good dining at about 50% off
--surf this site extensively
www.allearsnet.com
--if you have lil rugrats going do a character dining reservation. Cinderellas Breakfast and the Crystal Palace one with Pooh and friends are in the most demand.
--stay on the property itself if your budget allows. look into the extra magic hr to get zero wait times as well as the Eticket offer they do during the summer (park closes 3 hrs early and they sell passes to get in for 3 hrs with about 5,000 other people. zero waiting)
--Cirque Du Soleil is a big thumbs up
