OK, my first time at WDW was in 1985 when I was 8 years old. Then, my parents brought us back in 1989 when I was 12. I also went there twice in high school with the chorus (All American Music Festival), in 1992 at age 15 and in 1994 at age 17. Then, I didn't go back until I had my own family and we went on our first trip together in 2008 when I was 31.
So, I knew I was a Disney-holic when I went back in 2008 and fell in love with WDW all over again, but from an adult persepctive. I never thought I would enjoy it as much as an adult, until I started the trip planning for that one (and discovered the DIS!), and I became an obsessive planner.
A few signs of me being a Disney-holic:
1. I have to stop myself from referring to restaurant reservations here at home as "ADRs".
2. Sometimes I have the urge to refer to my husband as "DH" in normal conversation.
3. I really miss Mickey ice cream bars when I am not at WDW and I look in the grocer's freezer every time I go food shopping just *in case* they start selling them at supermarkets...VERY obsessive, I know!
4. I keep searching every now and then for places in NYC (my hometown) to see if they sell Dole Whip anywhere.
5. I found Dole Whips at Dutch Wonderland in PA and when we were there last October, I ate one...even though it was FREEZING outside...and I enjoyed every last bite!

6. I look at DVC
point charts "just for fun" to see where and for how long our points would allow us to go on future trips (even though we absolutely love our home, BWV).
7. I sometimes make Disney recipes at home.
8. I am always looking at park hours to see how I would plan my trip if I was there...just for fun.
9. I talk about WDW all the time!!!! So much that others frequently ask me for Disney advice...my family makes fun of me but then they thank me for being so obsessive with the planning that we don't wait on any super long lines and we have a very enjoyable time!
And I'm sure there are tons of other things about me that make me a Disney-holic. I am just as bad with cruises, by the way. I know all the deck plans, menus and ship facts before I go!
