When do you think the best time is to visit an apartment pool to get the most privacy?

This is my first time living in an apartment (I hate it, by the way). I figured while I'm being miserable that I might as well try to enjoy the perks of living here. The pool just opened up, and I was hoping to go get my tan on and perhaps do some laps. Swimming is great exercise! All I have to do is go get a key from the landlord, and I can use it anytime I want. When do you think the best time would be to visit to get as much privacy as possible? I was thinking perhaps early in the morning when the sun first comes out? Does anyone have any personal experience? Thanks in advance.
