The Poly is a great place to take pics! The only thing I would recommend is to choose a time that the sun won't be so bright. We did 11:00am in August and the sun really got in the way, some of our pics we have squinty eyes.
I got pics at sunset point, Poly, and along the lines of GF beach too. It's a great background and there's not alot of people in the way My pics are posted in my PJ
