18" from the pool is where the anchors are set. Steps and corners can get tricky, so 3 ft is good to have. Get a good, accurate drawing of your pool and the concrete, including steps, diving boards etc.. They will custom design a cover for you and send you a drawing to show where holes need to be. You can put posts in the ground outside the pad if needed.

I got a Loop-Loc for my 20X36 grecian from poolcenter.com for around $1275, which included everything needed to install. I bought a new 3/4" hammer drill bit for around $30 at Lowe's that did a fine job on the 36 holes I needed. Even if you have to buy the drill, installing it yourself is the way to go.
