Well, let's see... I was an infant when my mom took me to DL and we went about once a year for several years, seeing as we have family in the area. All of these trips were day trips.
Went to the MK for the first time when I was about 15, also for a daytrip. Had my first real vacation there (offsite) for a week when I was 25 with my DH.. so that was my first time touring Epcot and MGM/Disney Studios. We've been about every 3 years since then, always on site.
My children were : DS1=18 monts, DS2 5, DD 3
Had we been employed this last year, we'd have gone! Here's hoping for a profitable year so we can go again! My daughter finds hidden Mickey's in EVERYTHING.. it's a sign.
