Nikki, 33, a PR director from Chicago, showed up to the pool at the Four Seasons Las Vegas like she'd been doing this her entire life — which, honestly, she probably had. Navy string bikini, sunglasses, a book she didn't open. Forty-five minutes in, the lifeguard on duty made his third lap of the pool area in twenty minutes and was gently reminded by a supervisor that the deep end existed. (No one was swimming in the deep end. The lifeguard did not care.) Two guests in pool-view rooms called down to ask if the pool area would be "similarly staffed" the following morning. Nikki checked out the next day and left a five-star review mentioning the "attentive staff." She wasn't wrong. The other guests' reviews were significantly less charitable. Wait until you hear what happened at the swim-up bar.
