We took a taxi to Playa La Ropa ($4) in Zihuatanejo and had an enjoyable day at the beach. We payed $10 for two premium lounge chairs at a beachfront bar. We didn't find the free lounge chairs I saw in other reports. We were satisfied with our experience and the service that was forthcoming from the bar/restaurant. I don't know the name of the place but they had blue pads on the lounges and tan colored beach umbrellas.
There was all kinds of activity on the beach. Wave riders, parasails etc. We talked to others who went to Playa Las Gatas and had a similar experience although Las Gatas is much busier.
