hmmmm any thoughts would help or if you think i'm totally crazy let me know
I think your totally crazy!

(I mean that affectionately!)
You know how most women dream about the proposal, wedding, having children, etc? I think proposing is the
one thing that the guy is totally in control of, I don't know if I'd want to take that one thing away from him.
I was completely in the same boat as you, as noted in my planning journal. We actually started planning the wedding BEFORE he proposed, because he insisted on getting the ring first. I called him my Bass-ackwards Groom.
Maybe instead of actually proposing, you can ask him if you can start planning the wedding ahead of time, since there is so much is involved. It also wouldn't hurt to let him know that you think Disney is the most romantic place in the world to get engaged.
I know this is 2008, and things have changed, so please take my thoughts as intended...just my own opinion, as I don't know the dynamics of your relationship, this might be something he'd totally love.
Anyway, as to your question of how/where, gonna have to think on that one! Maybe since he's an Animal Science major, you can do it in front of one of the animal exhibits, and make some type of comment about how they mate for life, and how you feel he is your mate.
Good luck whatever you decide!
