I really am feeling a "Wish in the making" here, I feel guilty somehow that you seem to be like mirroring my obsession.
It is ALSO my dream to visit every single Disney park in the world one day & OBVIOUSLY I have the same problem that "once a year is no longer enough."
I am upset that I won't be visiting my best friend in Gent, Belgium this year 'cause it's SO easy to swing over to DLP.... I'll just have to live through you.
How is it even POSSIBLE that I've been in France twice, Belgium once, etc.. and STILL have NEVER BEEN TO DISNEYLAND PARIS?!?!
I did a cruise on the Seine also & it was really surreal. I know this sounds cliche but just passing by Notre Dame was surreal enough for me, like you couldn't even believe it was right there. I remember passing under really old looking gothic bridges that were just awesome and when we got further away from the main city area I remember seeing castle ruins that were gorgeous & other interesting stuff. It was a cool experience.
