The first time at WDW is truly overwhelming (the sights, sounds, smells, etc.); plus President's Week at WDW is now one of the most crowded times to visit--if not the busiest.
My best advice to you is to take as many pictures as you can to refresh your memory once you return home. Also, try to hit all the "E-ticket" rides and attractions at least once and then enjoy the other rides and attractions at your leisure. If you are going to be at WDW each day for 2 weeks you should be able to see and do everything.
