When we were at Disney in 2000 we traveled with our 2 kids (4 & 22 months) and my in-laws. My DH laughed at me because I did so much preplanning for the trip. He thought we should just go where the whim took us. My MIL, however, tells many people that without my planning we would have missed so many things. My DD opened Fantasyland one day. We had one PS scheduled per day (most days) and it was in the park we were at. My DD did the Wonderland Tea Party and was scheduled (but cancelled) for the Pirate Cruise. My DS had a nap everyday. We did the Illuminations Birthday Cruise and HDD.
Now we are scheduled to go in December and I am once again planning--and my DH is still laughing. My in-laws; however, know that when we get there I will have it all organized and we'll have a ball! This time we'll have 3 kids (7, turning 5 at WDW, and 19 months)
