I put panels to either side of my bedroom sliding door. We very seldom open the door as well; however, we did extend the rod about 15" to either side so that the panels stacked back to either side of trim so on those rare occasions when we do want to access the sliding door, the panels were not in front. The suggestion of a tie back is a good one if you do require more frequent access since I noticed if there is any wind, then the drapes will blow out the open sliding door and I have to be mindful of that when I close it. All and all, though, I much prefer the more balanced, symmetrical look of two panels; whether formal or informal.

I would definitely use curtains. They can be kept completely out of the way when using the door, they come in many fabrics and prices, and they can be washable. You could use grommet top panels on a decorative rod. They are very kid and pet friendly. In addition....I abhor roller shades...:)

Pictures please.

Have you thought about bottom up top down pleated blinds or honeycomb shades? Minimal in design and able to install as inside mount to a shallow depth of only 1/2 inch. Here are some client pictures and how they solved their bay window challenge.
