All beaches are public so, technically, you can take your own chairs to any beach. However, to be "polite" to the beach vendors, you should go to the "side" of any beach - meaning, not placing your chairs in the middle of their loungers. We've done this many times and, as long as you aren't inhibiting their business, they will pretty much leave you alone. Another benefit is that the folks selling jewelry, massages, hats, etc. won't really bother you if you're in your own chairs because you look like a local and not a tourist.
