Any advantge to doubling solar blanket?

Just a quick question from a forum newbie: the cool evenings in my area recently are killing our pool temps. I have a solar blanket which stays on at all times. I also have access to a second solar blanket - would there be any advantage to using both simultaneously, either by warming the water more during the day or decreasing the amount of heat lost throughout the night?

Any input would be greatly appreciated. We've got a pool party coming up next saturday, and at this point, I'm afraid it's going to be too cold to swim.

I wouldn't think there would be any advantage of using two. If someone has a different opinion, they will chime in.

Having solar panels on my pool is what made the big difference for my pool temps. (along with a solar blanket to keep the heat I gain during the day from being lost overnight.)
