Re: Playa Del Carmen
The 2 Maromas are of course the high end resorts in the MexRiv, so don't discount the restos on the beautiful grounds there.
They have van service to PDC, check the details and see how convenient it is or isn't. If you end up using taxis it would be to get to a special place in town. Top 5 are Cocina 38, Negrosal, Wicky's, John Grey's kitchen, and Yaxche. Only Yaxche is Mexican /Mayan.
If you want anything in particular or authentic, shout back.
