When i was kid growing up in Florida we went to Disney on average about once every 2 years. We did work in Universal as well and Busch Gardens (90's Busch gardens was a lot of fun as a kid). We never did the week long or longer vacations as we were not very well of financially, but my parents made the effort to go.
After I turned 14 and took my last trip with my mom and dad, I went to grad night my senior year, then not again to any theme park for over 10 years. My wife went to school UCF and had annual passes all 4 of her years there and she was quite Disney obsessed 9still is). She got me to go a few years after we got together and i got bit by the bug. We started going 2-3 times a year for short stays. i credit seeing dads with their kids at MK for making me officially ready for kids.
We continued this trend even after the kids came. i have a thread on here asking advice for out trip when was oldest was 18 months and mommy was 7 months pregnant with my little one. They are 8 and 6 now. Great trip BTW.
As time goes on though, we are starting to go less and less. It's just getting to be too much. We do good but dropping $2-4k on a weekend trip is just, well, a lot. So we have been going elsewhere.
