Fox Hollow-Centerpieces

Hello,

I am having some difficulty choosing centerpieces. I am in the Garden Terrace room and the tables are oval. Does anyone have any suggestions and/or pics of their reception at the Fox Hollow?
I was originally going with tall centerpieces with orchids but I am re-thinking that.

Please help....I am also thinking calla lillies....
I am soooooooooooooo bad at this...and I have NO help!!!
