Hi there and Congrats! I have been to WDW many times in early OCT as my b'day is Oct. 1 and I can tell you...it's HOT. If you can schedule the wededing for mid or even late OCT, you might have a better time, temp wise, but you never know with OCT weather down there in relation to rain etc.... I know there have been other weddings where the groom and ushers wear kilts, so hopefully someone can help you. I just wanted to mention, my DH is from Ireland and instead of doing a sand ceremomy, we did a Loving Cup, which is actually Scottish! It's called a quaich. Ours was actually the Irish version of the quaich and we had Mead in it. There's a bunch of info on-line about using the quaich in weddings and the ceremony it entails etc. Happy planning!! I love the Eau de France reception idea! Tell us more!
