And when I was in my 20s with no kids, I was teaching. I've switched careers to something more flexible, but by the time I did that, my oldest two were in school. Seems like I've traded inflexibility on my schedule for inflexibility on theirs. Clearly, I didn't adequately consider Disney vacations while making career and family decisions.
Fortunately, I can be flexible on my next trip, as it will be with DD only. She is 3 1/2, and my plan is to take her sometime when she is 4, probably next fall or winter. I want to take her the year before she starts school, as it will be the last time she really has that kind of freedom to go at a lower crowd time when I can get good flight prices. I figure 4 is also a good age because she will hopefully be tall enough for some of the good rides (aka rides I want to do) but still young enough to be awed by meeting "real" princesses.
