Well, here's my thoughts.
MY family has been Disney nuts for a long time. Born in San Diego, we went to Disneyland a couple of times when I was young (Under 5) I remember very little of the park, but do remember some things. At 5 we moved to the East coast (Virginia )and went to Disney World for the first time about a year after. A nice thing is that we always went in our trailer, so it made traveling a bit nicer for us. From the age of 5 on, we went to WDW a total of 15 times over 15 years. Two days after I gradutaed college I drove from Pennsylvannia to WDW to spend a week over Christmas with the family. My brother is five years older, and this was the last time we were able to be in WDW together as a family. However, the love didn't stop there.
While my parents have not returned to WDW for a number of years, they are still Disney fans. My dad not as much as my mom, but he always enjoyed his time in WDW (Spent fishing, listening to the radio and security (Really interesting to listen to that stuff)). But the love is still there. MY brother got married on the Disney Cruise so we were able to spend time there together. I've been to WDW a few more times for school and other things, as well as solo visits and still love that place more then any other place in the world. I literally could walk around blindfolded. You know your family is Disney nuts when you go for a month at a time, and spend maybe only half that amount actually in the parks.
Now I am back in California and have yet to visit Disneyland, but it is high on my list of things to do. My brother and his wife are Disney nuts as well, so it all fits in great.
