Congrats on narrowing down the guest list! That's a pretty big accomplishment!
We are getting married at noon at the Yacht Club Gazebo. With pictures and first dances and toast/cake, etc, we won't get to our "reception" at downtown disney until 2:30, so my centerpieces/favors tie into this. If you click on my planning journal below, on page two you'll see pics of my centerpieces and favors. Basically, I made them edible so the guests could munch on them. (We're having the limo pick up half the wedding guests and take them to the luncheon site, then coming back to pick the rest of us up. I didn't want those sitting at the restaurant to feel awkward about ordering appetizers without us OR sitting around and starving to death waiting for us; lol!)
I'm debating now whether to have the favors on the chairs at the ceremony (both to have something to munch on and to hold down our programs in case it gets windy) or save them and put them on all the plates at the luncheon.
We aren't having a rehearsal dinner, per se, but we're taking all of our out of town guests to Buca di Beppo (a family-style Italian restaurant off site) the night before, so we all have a chance to relax and catch up before the wedding. There won't be a reharsal, technically, so I'm just calling it a "pre-wedding dinner."
Hope that helps!
