I'm the main Disney nut in our house. DH couldn't care less, in fact he's not even going with us this trip, and it'll be our first time without him! Oh well! LOL!
DS11 and DS18 are into Disney, but they're not obsessed like me. But we still talk about our upcoming trip everyday, and we talk about our past trips a lot. I'm grateful that my boys are taking after me instead of after their dad, because I'm training them to be true Disney lovers!
As for extended family, they just don't get it at all, it's a been there done that mentality with them. Their loss!
