I know one thing to remember is that you can recycle the floral arrangements used in the ceremony so that you can use them in the reception as well. Try and figure out with your florist what arrangements would work for this.
For our menu, i wanted all choices possible, but later realized that it really wasn't all necessary and so I could have saved a buck or two with 2 choices (Chicken Marsala with steak or with another meat). I mean we can only eat so much, right?lol
And I have to tell you that by the time the DP rolled around we were all so stuffed that I really couldn't appreciate all the deserts. So in essence, its good to keep it simple with the meal, because it really is ALOT of food!!! and, you keep the cost down.
If you are using Disney floral, the nice thing is that you should be able to use the same decor for all the venues. This will definitely help to save!
Also, would you consider having an earlier ceremony to save, or are you really set on having the 2:30pm time slot?
I had the 2:30pm slot becuase it was more convinient for my guests, but I would have preferred something earlier to save a little more, ya know?
