We did just that on Liberty recently. Once opened it did eat up a bit of the space on one side of the balcony which made moving the chairs around less than easy, but doable. We never tried to close the partition after it was secured open but I am thinking that we would have had to request that too- in other words I do not think you can open and close it as you please. I may be wrong on that though. I see if I have any pics when I get home that show the setup.
