The Playa Paraiso that you are talking about is somewhere in between Cancun & Playa del Carmen. A real estate agent friend of ours bought a piece of land in that area and is planning to build in the near future. It is mostly a housing development I think?
I personally think that you would enjoy staying closer to Playa as it is more central & lively. It is certainly a good home base for all kinds of tours and activities in the area. Playacar is located right next to PDC and if you are close to the Reef Club, you can walk to PDC. Hope this helps.
