tinkerrn,
Hi! I just surprised my DH with the WL trip! He thought we were staying at POR, but I changed it on him without him knowing. Now our trip isn't until next week, but I couldn't hold the surprise in any longer, so here is what I did.
I bought an accordian photo album at Target. I wrote a little story about the upcoming trip and printed it out. I pasted the story into the accordian book and accented it with lots of Disney sticker. The last page was the "reveal" and I practically knocked DH off of his seat!
Other ideas I had included making a short video of myself telling him the news, waiting until we got to the Orlando International and handing him one of our WL refillable mugs and having my DS3 "spill the beans."
You could also get creative and "announce" at your wedding reception - if you're having one. Or be romantic about it and buy a card with a WL type theme and write a letter to him about how you want your honeymoon to be memorable and romantic, so you have a surprise for him.
I have an extra WL magnet if you want, I could mail it to you. PM me if you're interested. It's the kind that you put a photo in so you could put a picture of the two of you in the magnet and say something like, "Imagine us here, at the WL."
Let me know if you're interested in that!
Happy planning!!!!!!!!
