We got engaged almost a year and a half years ago, in February 2012. I was in between jobs at the time, and we decided to go to Disney World for a week, since I'm a big Disney fan but have never been to Disney World before.
On our second night at Disney, we had a dinner reservation at Cinderella's Royal Castle:
We continued to wander around Magic Kingdom afterwards and came across Tinker Bell's Magical Nook. We didn't know if the nook was still open as it was close to midnight at that point, but and as it turns out, Tinker Bell and her friends were there! They made a big scene when then found out we just got engaged. Here is a picture of us totally embarrassed by all the attention:
Tinker Bell LOVED my engagement ring. This is one of my favorite pictures - Tinker Bell's eyes were so dramatic!
It was the PERFECT proposal. Not to mention Disney gave us these "Just Engaged" buttons so for the rest of the trip all the cast members and other guests kept congratulating us. :)
