Any former Pedestals brides out there that can help me?

I have my final meeting tonight and I feel totally unprepared. What should I have with me besides swatches? I'm going to see my centerpiece....anything else I should be prepared to ask?

Any advice much appreciated.

I didnt use pedestals but my florist had to see it
a full length one so that they know who long to make your bouquet if its cascade
