It was just my DH and me for our wedding three years ago.
It was probably the most magical, romantic day of our lives! Just being together at Disney to say our vows was such a dream come true!
The only extras I added were to have an extra bottle of the champagne (we ended up saving it for our first anniversary). And I pre-ordered all the proofs from our package photography.
We called in late April for a September wedding so you should have plenty of time to get things in order!
Our ceremony was at Sea Breeze Point and I chose all Disney songs for the violinist to play.
Our officiant was Rev. Kevin Knox and he allowed us to customize our vows for us (using samples he sent). We loved Rev. Knox and highly recommend him but other officiants will let you customize things a bit too!
We wanted a very casual wedding and asked Rev. Kevin not to wear his robes or a jacket...he was pleased to accommodate us because it was so hot that day!
My coordinator held my bouquet during our ceremony and she also held my cell phone so my mom could hear from Ohio.

Mom cried, of course. It was all DH and I could do NOT to cry!
After the ceremony we wandered around MGM (now DHS) for a couple of hours before getting ready to have our wedding dinner at the California Grill. We got a table right near the window so we had excellent seats to watch Wishes that night.
It was easily the best day of my life (even if my feet hurt by the end of the night).
If you are thinking about doing this, don't hesitate!!! You will not regret it at all!! If you have any other questions, just let me know!
