Three times. My DH and I started taking my little one when she was three. I don't know who was more excited, me or her. Since then, we've gone every other year. Can't wait for this summer for our much anticipated fourth trip!
My first trip was in 2007. I've been 5 more times since then and have 2 trips planned for this year. I guess you could say that first trip made a big impression on me!
Our first time was in 1987, then we didn't go back until 2010 - I wanted to turn 50 there. We had such a good time, we have been back three more times and have another trip planned for April.
Trip #14 is coming up in October. I went twice as a child and I've taken DS every year since 2001. We weren't planning to go this year, but after thinking about it, I just couldn't bear the thought of not spending a little time at WDW. So we're going for 4 days this fall.
