This is such a great idea. Im sure your wife will love it. And theres so much at Disney that misdirecting her should be easy!
Okay, I dont have any full poems, but heres a few you could use!
Beneath the tower we can stand
Arm in arm, hand in hand,
And of course, we will not miss
Experiencing a goodnight kiss.
Referencing the Goodnight Kiss, but it could also be thinking kissing under the Eifle Tower in Paris.
Around the world in less than 80 days
Could thrill us both in so many ways.
Referencing the world showcase, but the book to which the title refers has a lot of the setting actually happening in Europe.
We can stroll along the river bank
Where the artist works on his canvas blank.
It looks like he has taken a break,
Lets go look out over the lake.
Referencing the painting in progress on the painters easel which is on the bank in France at Epcot. Also, the lake at the center of World Showcase. But it also tends to add to the french flavour of some of the other clues.
