I've lived about 3 hrs away from WDW my entire life, and in my early childhood we would go once a year, usually in September, but I can clearly recall only two of them (one of which was my first visit to EPCOT in 1984). I looked through some old family photo albums the last time I visited my parents, and as near as I can tell our family made four of those trips. Additionally, my grandfather took me to EPCOT twice in the '80s, in 1986 and 1989. The 1989 trip was the last time I saw World of Motion.
We made only two trips in the '90s; one to the MK in 1992 (the last time I saw 20k and Mr. Toad's Wild Ride) and one to EPCOT in 1996 (the last time I rode Horizons and the original JII-curse you, Dr. Nigel Channing!)
Mrs. Future Guy and I were married on October 27, 2001, and we honeymooned at WDW for 3 days. We went back for a four-day trip in 2004, and then another 3-day trip in 2007. We got our APs in September of this year, and since then we've been twice (to the Studios on Labor Day and to the MK and EPCOT on Oct.26)
So that's 13 times, in total. And I'm only two weeks and a few days away from trip no. 14 on Jan. 3-7.
