A stealthier option is exploiting a delivery loophole. Order food or a package to a resident on the 8th floor—find a name via mailroom observation or a quick “forgot my floor” chat with the concierge beforehand. Pose as the delivery person, get buzzed up, and “accidentally” linger by the pool. You’d need to scope out a resident’s name first, which might take some recon, but it keeps your friend out of it.
