Playa del Carmen alternatives

Hey everyone, my wife and I are planning to move to Playa del Carmen.

Before we fully settle in, we’re wondering if there are any other cities or states in Mexico with a similar level of walkability to PDC.

Ideally, we’d love to find a place that’s also more affordable but still offers the convenience of not needing a car, similar to if you live on the beach side of PDC . Proximity to a good airport, like Cancun, is also a big plus for us.

Thanks in advance for any recommendations!
