Yep, count me in.
We made our first WDW trip this past May. I spent 3 months reading guidebooks, browsing the DIS and TGM, watching the planning DVD, etc. I spent so much time on it and was so obsessed that my wife pretty much banned me from saying the D word. You know you are going overboard when even your kids don't want to hear about Disney anymore. I'm not normally an organized person, so DW thought it was pretty amusing that I was making up itineraries and putting together information booklets with touring plans, parade viewing tips, etc., etc. She made fun of me quite a bit.
But our trip was so much fun that now she almost "gets it". So now that I'm planning for our trip next March, she doesn't complain about my planning at all. She gives me the occasional eye roll and smile, but no complaining.
